Description

Benzenesulfinamide, 2-Ethoxy-, [S(S)]- (9Ci) is a chiral, organosulfur compound featuring a sulfinamide functional group, a key intermediate in asymmetric synthesis. Its value lies in its role as a versatile chiral auxiliary or ligand for constructing stereogenic centers in pharmaceutical and fine chemical manufacturing. This high-purity intermediate is essential for research and development chemists and production facilities in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop enantiomerically pure active ingredients.

Application

• As a chiral auxiliary in the asymmetric synthesis of pharmaceutical intermediates.
• Utilized as a ligand precursor for transition metal catalysis in enantioselective reactions.
• Key building block for the research and development of novel active pharmaceutical ingredients (APIs) with specific stereochemistry.
• Intermediate in the synthesis of agrochemicals such as herbicides and fungicides requiring chiral purity.
• Used in academic and industrial methodology development for new sulfinamide-based transformations.
• Potential application in the synthesis of functional materials and specialty polymers.
