By seamlessly integrating analytics into R&D workflows, BOC Sciences helps clients identify potential risks early, refine key development parameters, and lay the foundation for smooth process scale-up and quality management.
Biochemical samples often feature complex matrices, characterized by high salt concentrations, protein content, or multi-component formulations, that pose significant analytical challenges. With extensive experience in complex sample handling and detection, BOC Sciences offers the following targeted solutions:
Multistep sample pretreatment strategies: Including solid-phase extraction (SPE), liquid-liquid extraction, and derivatization to enhance analyte enrichment and stability while minimizing interference.
High-resolution, multidimensional separation techniques: Utilizing tools such as 2D-LC, UHPLC, and selective detectors to effectively isolate target compounds from background noise.
Integrated multi-angle detection platforms: Combining techniques like LC-MS/MS and ICP-MS to provide both qualitative and quantitative assurance.
Method robustness and reproducibility testing: Verifying performance across multiple batches, instruments, and operators to ensure method consistency in real-world applications.
BOC Sciences' technical team customizes the analytical approach based on each project's unique needs, selecting optimal platforms and optimizing conditions to deliver accurate, reliable data, particularly in complex sample matrices. This enables clients to maximize the interpretive power of their analytical data and make well-informed decisions throughout the development lifecycle.
BOC Sciences operates a state-of-the-art analytical instrumentation platform that comprehensively encompasses high-performance liquid chromatography (HPLC), gas chromatography (GC), liquid chromatography-mass spectrometry (LC-MS), nuclear magnetic resonance spectroscopy (NMR), and a range of molecular spectroscopic techniques including UV-Vis, FTIR, and fluorescence spectroscopy. These core technologies form the backbone of our analytical method development and quality control capabilities, enabling us to handle chemically and biochemically complex samples characterized by intricate structures, high bioactivity, and diverse impurity profiles.
HPLC/UPLC Systems: Ideal for the separation and quantification of small to medium-sized molecules, organic impurities, degradation products, and polar compounds. These systems offer high resolution and throughput, and are routinely employed in purity assessment, dissolution profiling, and residual solvent analysis.
GC-FID/GC-MS Platforms: These platforms are particularly suited for the accurate measurement of volatile organic compounds, residual solvents, and fatty acid compositions, especially in samples with high thermal stability.
LC-MS/MS Systems: Capable of delivering high sensitivity and selectivity even in complex matrices, LC-MS/MS is extensively used for trace impurity identification, metabolite analysis, and the characterization of stability samples.
NMR Spectroscopy: Offers high-precision data for structure confirmation, stereochemical analysis, and impurity identification. NMR provides complete molecular framework elucidation, making it indispensable in comprehensive structural studies.
Spectroscopic Techniques (UV, FTIR, CD, etc.): Provide effective support for functional group analysis, conformational studies, and characterization of protein-small molecule interactions. These methods are rapid, non-destructive, and highly efficient.
BOC Sciences leverages these technologies in a flexible and project-driven manner, assembling multi-dimensional and multi-perspective analytical systems tailored to specific client needs. This integrated approach significantly enhances the depth and accuracy of sample characterization, ensuring the scientific robustness of the resulting data.

Impurity control is a critical factor in maintaining product quality and optimizing manufacturing processes. BOC Sciences brings extensive expertise in impurity profiling and quantification strategies, enabling comprehensive identification of impurity types, elucidation of their formation pathways, and assessment of their potential impact on product attributes. These insights lay the foundation for data-driven process improvement and quality assurance. Our services include but are not limited to:
Comprehensive Impurity Profiling: By collecting samples under varying reaction and storage conditions, we systematically catalog all potential impurities and establish a traceable, reproducible impurity profile database.
Quantification of Known Impurities: We develop highly stable, linear, and sensitive quantification methods for known impurities, ensuring accurate measurement even in complex sample matrices.
Structural Elucidation of Unknown Impurities: Utilizing a combination of LC-HRMS, GC-MS, and NMR, we provide definitive identification and source tracing for newly observed impurities.
Optimization of Resolution Between Main Components and Impurities: Through tailored chromatographic conditions and selection of appropriate stationary and mobile phases, we enhance the separation efficiency between target compounds and impurities, thereby improving quantitative accuracy.
Development of Ultra-Trace Detection Methods: We design highly sensitive methods capable of detecting impurities at ppb levels or lower, to support stringent quality requirements for high-purity products.
At BOC Sciences, impurity analysis is not limited to generating analytical data, it involves a mechanistic understanding of impurity formation and practical integration with process knowledge. Our approach helps clients mitigate impurity risks from the outset, enabling forward-looking and systematic quality control throughout the product lifecycle.

In biochemical research and product development, the structural complexity, physicochemical properties, and stability of different molecular classes vary significantly. Therefore, analytical strategies must be customized accordingly. BOC Sciences fully understands the characteristics of each molecule type and offers tailored analytical method development services for small molecules, peptides, for small molecules, peptides, and oligonucleotides.
Small Molecules: These compounds often exhibit structural diversity and broad impurity profiles. BOC Sciences utilizes high-resolution chromatographic systems (HPLC/UPLC), GC-MS, LC-MS, and selective detectors (UV, fluorescence, MS-based) to achieve accurate separation and quantification of both main components and trace impurities. These methods are widely applied in purity determination, dissolution profiling, and residual solvent analysis.
Peptides: With high polarity, conformational dependence, and inherent instability, peptides pose unique analytical challenges. Our strategies involve reversed-phase HPLC, peptide-specific columns, and LC-MS/MS techniques to monitor sequence integrity, terminal modifications, oxidation/deamidation, and aggregation. We also evaluate isomeric forms and structural heterogeneity to ensure comprehensive peptide characterization.
Oligonucleotides: Due to their strong negative charge and tendency to form secondary structures, oligonucleotides require specialized methods. BOC Sciences employs ion-pairing HPLC, ESI-MS, and capillary electrophoresis (CE) to tackle their separation and quantitation, with proven success in detecting chain-length variants, truncated fragments, and phosphorylation patterns.
For each molecular class, our expert team develops not only robust and selective methods but also ensures their reproducibility and transferability across platforms, enabling reliable data generation throughout the development cycle.
Analytical method development must go beyond final product testing to include comprehensive control of key intermediates throughout the synthetic process. BOC Sciences delivers full-spectrum solutions for quality analysis of raw materials, intermediates, and final active ingredients:
