BOC Sciences offers comprehensive process optimization services tailored to the unique requirements of small molecules, complex intermediates, and novel therapeutics. By leveraging advanced statistical methodologies and state-of-the-art technologies, we help clients identify critical process parameters, optimize yields, and establish reliable manufacturing protocols, providing a seamless transition from the laboratory to large-scale production.
BOC Sciences delivers data-driven process optimization strategies to enhance yield, reduce costs, and accelerate your path to large-scale production.
We utilize multi-variate statistical DoE approaches to simultaneously evaluate the interactions between multiple critical process parameters, rapidly identifying the optimal operating space with fewer experiments.
Implementation of Process Analytical Technology (PAT) tools, such as in situ FTIR and Raman spectroscopy, allows for real-time tracking of reaction progress, intermediate formation, and endpoint determination.
Our parallel synthesis platforms enable the rapid, automated screening of hundreds of reaction conditions, catalysts, and solvent combinations to identify the most promising variables in a fraction of the time.
For hazardous, highly exothermic, or extremely fast reactions, we design continuous flow processes that offer superior heat and mass transfer, improved safety profiles, and consistent product quality compared to traditional batch processing.
We establish the origin and fate of impurities throughout the synthetic route. Our impurities synthesis and isolation capabilities aid in characterizing by-products, allowing us to design steps that effectively purge them.
We actively evaluate processes through the lens of green chemistry, focusing on reducing the E-factor (environmental impact), minimizing toxic solvent usage, and improving atom economy for sustainable scale-up.
BOC Sciences adapts optimization strategies to accommodate the specific chemical behaviors and handling requirements of diverse molecular classes.

Our chemists replicate your existing procedure to establish baseline metrics (yield, purity, impurity profile) and identify critical pain points such as low-yielding steps, expensive reagents, or hazardous operations.
Using DoE and parallel screening, we systematically optimize reaction conditions, solvent systems, and work-up procedures at the milligram to gram scale to establish a robust and efficient operating window.
The optimized process is scaled up in our state-of-the-art kilo labs. This stage verifies the scalability of the chemical engineering parameters, addressing heat/mass transfer issues that only appear at larger scales.
We compile comprehensive process development reports, finalized batch records, and validated analytical methods, ensuring a seamless and risk-free technology transfer to the final manufacturing facility.
We assist early-stage companies by rapidly converting medicinal chemistry routes into scalable processes, providing the crucial material needed for advanced toxicity studies and late-stage development milestones without draining limited funding. Our process optimization support helps startups improve route robustness, control key impurities, and prepare for smooth scale-up as projects move toward IND-enabling and early CMC activities.
For established pharma facing margin pressures, we execute "second-generation" route scouting and late-stage process optimization to significantly reduce the COGs and streamline supply chains for commercialized assets. We also help improve process reliability, raw material efficiency, and manufacturability, supporting more consistent production and easier technology transfer across development and commercial teams.
Acting as a dedicated chemistry extension, we offer end-to-end custom synthesis and process management for virtual entities lacking internal labs, ensuring their assets transition smoothly from discovery to pilot scale. With practical support in route selection, process troubleshooting, and CDMO coordination, we help virtual companies maintain project momentum while managing cost, quality, and timeline expectations.
We help academic researchers bridge the "valley of death" by translating innovative but impractical benchtop syntheses into robust, reproducible processes suitable for broader industrial application or out-licensing.

Client Needs: A mid-size pharmaceutical developer had a late-stage compound synthesized via a 7-step route. However, step 5 involved a problematic cross-coupling reaction with a highly variable yield (30-55%) and difficult impurity removal, making the overall process economically unviable for larger scale.
Challenges: The catalyst used was prone to degradation, and the by-products co-eluted with the desired intermediate during standard crystallization, necessitating expensive chromatographic purification.
Solution: BOC Sciences initiated a HTS campaign to evaluate over 90 catalyst/ligand and solvent combinations. Through DoE, we identified a robust palladium-based catalytic system and optimized the reaction temperature. Furthermore, we engineered a solvent-swap strategy that forced the specific precipitation of the desired intermediate.
Outcome: The yield of step 5 consistently improved to 85%. The new crystallization protocol completely eliminated the need for column chromatography, reducing the overall COGs by 40% and providing a highly reproducible process ready for multi-kilogram production.
Client Needs: A biotech client needed to scale up an advanced intermediate for their target molecule. The original discovery route utilized a highly explosive azide reagent, which posed unacceptable safety risks for any scale larger than a few grams.
Challenges: The client required a new synthetic route that avoided azides entirely while maintaining the correct stereochemistry of the final intermediate. Time was critical, as material was urgently needed for downstream formulation studies.
Solution: Our process R&D team performed extensive route scouting to find alternative methodologies for introducing the required nitrogen functionality. We developed a novel, azide-free, 3-step sequence utilizing an enzymatic amination strategy. We then conducted rigorous thermal hazard testing (DSC) to confirm the safety profile of the new intermediates.
Outcome: The newly developed route successfully bypassed all explosive hazards. The stereochemical purity was maintained at >99% ee. The process was safely demonstrated at the 5 kg scale in our kilo lab, allowing the client to meet their development timelines without compromising safety.
Client Needs: A company approached us with a functional, multi-step synthesis for a specialty building block, but the process was labor-intensive, taking over three weeks per batch due to multiple isolation and drying steps.
Challenges: Each intermediate isolation led to a 5-10% mechanical loss of material. The extended processing time significantly bottlenecked the client's internal supply chain.
Solution: BOC Sciences evaluated the physical properties and stability of the intermediates. We successfully "telescoped" three consecutive steps—meaning the reactions were carried out sequentially in the same reactor without isolating the intermediates. We optimized the reagent stoichiometry and introduced a liquid-liquid extraction procedure between steps to purge water-soluble by-products without precipitating the main product.
Outcome: The telescoping strategy reduced the batch cycle time from 21 days to just 8 days. Furthermore, by eliminating the mechanical losses associated with intermediate isolation, the overall yield across the three steps increased by 18%, significantly boosting the throughput of the manufacturing process.
A data-driven approach can be used to comprehensively evaluate existing processes, including material balance, energy utilization, and efficiency of critical steps, enabling rapid identification of bottlenecks affecting capacity or cost. By combining multi-parameter modeling with experimental validation, key influencing factors can be clarified and targeted optimization strategies developed, ultimately improving process stability and resource efficiency.
During scale-up, it is essential to focus on changes in mass transfer, heat transfer, and mixing behavior, while establishing reliable scale-up models based on lab and pilot data. Systematic parameter mapping and risk assessment help minimize deviations. Service providers like BOC Sciences, with extensive scale-up experience and technical platforms, can support clients in achieving smooth and consistent transitions.
Multivariate optimization uses design of experiments (DoE) and statistical analysis to evaluate the impact of multiple parameters simultaneously, significantly enhancing development efficiency. Compared to single-factor methods, it reveals interactions between variables more comprehensively, helping define optimal process windows. This approach is particularly valuable for complex systems, reducing resource waste and improving reproducibility.
Outsourcing process optimization to specialized providers offers access to cross-disciplinary expertise and established development systems, avoiding internal resource fragmentation. For example, BOC Sciences integrates advanced analytical tools with experienced R&D teams to deliver customized optimization solutions, helping accelerate development and improve project success rates while strengthening overall competitiveness.
Effective process optimization not only focuses on performance improvement but also considers raw material utilization, energy consumption, and operational complexity. Through systematic analysis and process refinement, it is possible to enhance performance while controlling overall costs. Implementing continuous improvement and data feedback mechanisms supports long-term cost efficiency and stable process performance.
Our medicinal chemistry route was far too costly for scale-up. BOC Sciences completely redesigned the synthesis, cutting out two steps and replacing a very expensive catalyst. The new process is elegant, robust, and saved us a tremendous amount of money.
