BOC Sciences provides expert microchannel reaction services to overcome synthetic bottlenecks and enhance R&D efficiency.
Microchannel reactors offer uniform irradiation and superior light penetration compared to batch vessels. We utilize this advantage to perform efficient photocatalytic reactions, accessing unique chemical spaces and complex scaffold constructions.
Our systems operate safely at elevated temperatures and pressures ("Novel Process Windows"), enabling reaction rates that are orders of magnitude faster than conventional reflux methods, ideal for stubborn substrates.
By minimizing the distance between electrodes in micro-reactors, we achieve high current efficiency and precise control over oxidation/reduction potentials, facilitating green chemistry approaches without chemical oxidants/reductants.
Leveraging micromixing technology, we handle extremely fast reactions (milliseconds to seconds) that require kinetic control. This prevents side reactions and improves the chemo- and regioselectivity of the target molecule.
We link multiple reactor modules to perform sequential synthesis without isolating intermediates. This approach is vital for handling unstable species and reducing solvent usage and handling time in complex synthetic routes.
Using immobilized catalysts in packed-bed micro-reactors, we conduct efficient hydrogenation and other gas-liquid-solid reactions. This setup eliminates catalyst filtration steps and enhances safety when handling hydrogen gas.
BOC Sciences leverages advanced microchannel reactors to handle a wide spectrum of challenging chemical transformations, ensuring safety and efficiency for diverse reaction types.

BOC Sciences resolves selectivity issues (e.g., mono- vs. di-substitution) often encountered in batch mixing. By controlling mixing at the micro-scale and precisely managing residence time, we suppress over-reaction and side-product formation, delivering higher purity intermediates for drug development.
We unlock chemical routes previously deemed too dangerous for R&D laboratories. Our microchannel platforms safely handle explosive intermediates (like azides or diazo compounds) by generating and consuming them in situ, expanding the accessible chemical space for medicinal chemists.
Our continuous flow photoreactors solve the scalability issues of batch photochemistry. With maximized surface-to-volume ratios, we ensure uniform photon flux, enabling efficient photoredox transformations that are crucial for modern late-stage functionalization of drug molecules.
We assist discovery teams in rapidly scouting new synthetic routes. Our high-throughput flow platforms allow for the quick evaluation of diverse conditions and reagents using minimal material, significantly shortening the "design-make-test" cycle in lead optimization.

Microchannel geometries provide exceptional surface-area-to-volume ratios, preventing hot-spots and ensuring uniform reaction conditions that are impossible in large batch reactors.
The minimal active reaction volume significantly reduces the risk associated with hazardous reagents and highly exothermic reactions, protecting personnel and facilities.
Continuous flow allows for automated parameter screening. Conditions can be changed on the fly, providing rich data sets and optimized processes in a fraction of the time required for batch.
Flow chemistry enables the use of extreme conditions (high T/P) and unstable intermediates, allowing chemists to access novel structures and synthetic shortcuts.
Client Needs: A medicinal chemistry team needed to perform a selective lithiation-substitution on a sensitive heteroaromatic scaffold. Batch attempts resulted in significant byproduct formation due to poor temperature control and slow mixing.
Challenges: The lithiated intermediate was extremely unstable even at -78°C, decomposing rapidly before the electrophile could be introduced. The accumulation of byproducts complicated purification and lowered yield to unacceptable levels (<15%).
Solution: BOC Sciences engineered a customized microchannel platform featuring superior heat exchange capabilities, enabling precise temperature control without the need for deep cryogenics. By fine-tuning residence times to the millisecond range, we achieved exact kinetic control over the lithiation and quenching steps, effectively suppressing side reactions and stabilizing the transient intermediate in a continuous stream.
Outcome: The flow process suppressed decomposition pathways, increasing the isolated yield to 78% and significantly improving purity. The method was successfully used to generate gram-scale quantities for biological testing.
Client Needs: A client required a scalable method for a [2+2] photocyclization to construct a strained cyclobutane ring system, a key motif in their lead candidate.
Challenges: In traditional batch photoreactors, light penetration was poor, leading to reaction times exceeding 48 hours and significant polymeric side-products. The process was unscalable and created a bottleneck for the project.
Solution: We deployed a high-efficiency continuous flow photoreactor designed to maximize photon flux density through an optimized surface-area-to-volume ratio. Our team systematically screened and optimized critical flow parameters—including light intensity, specific wavelength, and flow rate—to ensure uniform irradiation and rapid conversion, effectively overcoming the mass transfer limitations inherent in traditional batch vessels.
Outcome: Reaction time was reduced from 48 hours to 20 minutes. The continuous process delivered consistent material quality with a 90% yield, allowing the client to rapidly access the desired scaffold for further functionalization.
Client Needs: A biotech company needed to synthesize a library of organic azides for click-chemistry applications but lacked the specialized facilities to handle potentially explosive azide reagents safely.
Challenges: The synthesis involved the use of hazardous hydrazoic acid equivalents. Batch synthesis posed severe safety risks due to the potential for accumulation of explosive intermediates, limiting the client's ability to explore this chemical space.
Solution: To bypass safety constraints, BOC Sciences implemented a robust in situ generation and consumption protocol within a closed microfluidic system. This approach maintained the active volume of hazardous azide at negligible levels while "telescoping" the intermediate directly into the subsequent click reaction, thereby ensuring intrinsic safety and eliminating the need for isolation.
Outcome: We successfully delivered a library of 20 distinct azide intermediates without safety incidents. The robust flow protocol allowed for safe handling and subsequent "telescoped" click reactions, accelerating the client's library expansion.
Flow rate directly affects residence time, mixing efficiency, and product distribution. By calculating Reynolds numbers and analyzing reaction kinetics, the optimal flow range can be determined to achieve uniform reactions and high conversion. BOC Sciences provides fluid dynamics simulation and experimental validation services, helping clients precisely control flow rates for stable and efficient microreactor processes.
Microchannel materials must balance chemical compatibility, thermal conductivity, and pressure resistance, with different reactions requiring different material properties. BOC Sciences offers material evaluation and customized solutions based on reaction characteristics, ensuring long-term stable operation under high temperature, high pressure, or complex chemical environments while optimizing heat management and reaction efficiency.
Mixing efficiency determines reaction uniformity and selectivity. Optimizing channel structures, flow ratios, and inlet designs can enhance mixing under laminar or turbulent flow. BOC Sciences provides microchannel design optimization and computational fluid dynamics (CFD) simulation services, helping clients achieve efficient mixing, improved conversion, and better process controllability.
The high surface-to-volume ratio of microchannels enables rapid heat transfer, but precise control is still required for stable reactions. Designing heat exchange systems or integrating temperature control units can optimize local and overall temperature. BOC Sciences supports temperature control scheme design and experimental validation, ensuring efficient and stable continuous-flow reactions under varied conditions.
Yield depends on residence time, flow rate, channel design, and reaction conditions. Multi-parameter optimization, online monitoring, and reaction modeling can achieve high conversion and selectivity. BOC Sciences offers full support from microchannel design and fluid dynamics optimization to process scale-up, helping clients establish continuous-flow systems with stable high yields.
