BOC Sciences offers custom synthesis and manufacturing services for biotechnology, pharmaceutical, life science, chemical research, and related industries. A series of chemical reactions are carried out for the purpose of obtaining one or more organic molecules. As an integral part of drug discovery or other chemical industries, chemical synthesis plays an important role in the screening of numerous potential active ingredients. Leveraging this expertise, BOC Sciences provides comprehensive capabilities including API synthesis, chiral synthesis, bioconjugation, stable isotope labeling, multi-type reaction development, and process R&D, supporting synthesis from milligram to kilogram scale with full analytical documentation and traceability to efficiently meet diverse research and development needs.
Active pharmaceutical ingredient (API) is a part of a drug product that produces primary therapeutic effects. Some kinds of dosage forms, such as compound preparation, possess two or more active ingredients that is designed to treat different symptoms or integrate synthetical effects. BOC Sciences provides comprehensive API synthesis services, including custom design, process development, and scalable production, ensuring high purity and consistent quality to meet diverse research and commercial needs. Our expertise supports efficient and cost-effective API supply for pharmaceutical development projects.
Chiral synthesis, also known as enantioselective synthesis, has a great importance in the screening of APIs and development of bio/pharmaceutical products. BOC Sciences offers professional chiral synthesis services, including the design and optimization of enantioselective routes, scalable production of optically pure compounds, and analytical support to ensure high enantiomeric purity. Our capabilities help accelerate drug discovery and development by providing reliable and efficient solutions for complex chiral molecules.
Bioconjugation represents the technique of giving a target substance with certain desired properties through the site-specific reaction between the biomolecules and exogenous moieties (usually one or several other molecules). Through such covalent linkage approach, a broad range of innovative drug substances or end products are designed to improve the accuracy of disease diagnosis, pharmacokinetic properties, treatment efficacy and many other aspects. BOC Sciences offers tailored bioconjugation services, delivering precise and customizable molecule-linking solutions.
The practice of stable isotope labeling is a widely utilized method across the scientific disciplines, spanning chemistry, biology, and environmental science, among others, in order to effectively monitor the migration of atoms or molecules within a given system. The process itself involves the substitution of one or more atoms present within a molecule with a stable isotope of the identical element, wherein the likes of carbon-12 is supplanted by carbon-13, for example. BOC Sciences specializes in the custom synthesis of small molecules, including 13C-, 15N-, and 2H-labeled compounds and other isotopic products for drug development.
Chemical reactions are the processes by which chemicals interact to form new chemicals with different compositions. Simply stated, a chemical reaction is the process where reactants are transformed into products. How chemicals react is dictated by the chemical properties of the element or compound-the ways in which a compound or element undergoes changes in composition. BOC Sciences provides expertise in reaction development, optimization, and scale-up to support efficient chemical synthesis for research and industrial applications.
An effective process R&D is an essential part of your drug development while it plays important role in controlling costs, ensuring product's quality and meeting the requirements of regulations. More importantly, package solutions are available to address any problems and potential risks that significantly impact the quality of your products. BOC Sciences offers comprehensive process R&D services, including route optimization, scale-up, and troubleshooting, providing reliable and efficient support to enhance productivity and streamline pharmaceutical development.

Designing a synthetic route requires a comprehensive assessment of the target molecule’s structural complexity, functional group distribution, and potential reaction pathways. Common strategies include retrosynthetic analysis to deconstruct the target, selection of efficient and controllable key intermediates, and optimization of steps based on literature or database experience. For complex molecules, computational chemistry tools can help evaluate reaction feasibility and potential side reactions, significantly improving the likelihood of success. BOC Sciences can provide clients with tailored synthetic route evaluation and optimization, ensuring scientifically robust design.
The feasibility of a custom synthesis largely depends on the chemical stability and reactivity of the target molecule, as well as the availability of starting materials and intermediates. Molecules with high structural complexity, stereochemical requirements, or sensitive functional groups typically present higher challenges. Additionally, the choice of solvents, catalysts, and reaction conditions directly affects reaction efficiency and reproducibility. Experienced synthesis teams can leverage accumulated chemical knowledge and experimental expertise to assess the feasibility and optimization potential of different approaches for clients.
Strategies to minimize by-products include selecting the most suitable reaction pathway, controlling reaction temperature and time, employing protecting group strategies for sensitive functional groups, and using highly selective catalytic systems. In multi-step synthesis, monitoring and purifying intermediates is also critical. These measures can significantly improve overall yield and product quality, providing reliable material for subsequent applications.
Scaling up from milligram to gram quantities requires consideration of heat management, mixing uniformity, and changes in reaction kinetics. Conditions that are stable at a small scale may lead to side reactions or lower yield when scaled up. Therefore, stepwise scale-up and staged optimization are necessary. BOC Sciences can offer scientifically informed adjustments during scale-up to ensure a smooth transition to larger quantities.
Ensuring product purity and consistency relies on precise control of reaction conditions, the use of highly selective reagents, and rigorous monitoring and purification of intermediates. In multi-step syntheses, quality control at each stage is critical to guarantee the stability of the final product. BOC Sciences leverages standardized procedures and accumulated expertise to provide clients with high-quality, reproducible custom products.
