Profile: BOC Sciences provides a wide variety of custom services which range from bulk compounds to specialty species in the pharmaceutical, agrochemical, and biotechnology industries. We offer the design and synthesis of multipurpose screening compounds to meet the exact screening requirements. Specify compounds, quantities, format (dry/solid or DMSO) and the tube, vial or plate required to complement the compound handling system. Chiral synthesis (enantioselective synthesis, also called asymmetric synthesis) is the synthesis of a compound by a method that favors the formation of a specific enantiomer or diastereomer. It is a key process in modern chemistry and is particularly important in the field of medicinal chemistry, as the different enantiomers or diastereomers of a molecule often have different biological activity.
