Custom Synthesis

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.

Custom Synthesis

Our custom chemical synthesis services include, but are not limited to, the following:

Active pharmaceutical ingredient (API) is a part of 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.

Chiral synthesis, also known as enantioselective synthesis, has a great importance in the screening of APIs and development of bio/pharmaceutical products.

Recognizing the increasing importance of radiometric detection in drug discovery and development, radiolabeled chemical synthesis is hence become a highly concerned area in the pharmaceutical industry.

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.

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.

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.
