Description

Ethanesulfinic Acid, 2-[[(1,1-Dimethylethoxy)Carbonyl]Amino]- (9Ci) is a high-purity, specialized organic building block featuring a unique sulfinic acid moiety protected by a Boc (tert-butoxycarbonyl) group. This compound matters as a critical intermediate for the synthesis of novel pharmaceuticals, agrochemicals, and advanced materials, enabling precise molecular construction. It is primarily needed by research chemists and process development scientists in the pharmaceutical and fine chemical industries for constructing complex sulfonamide derivatives and other sulfur-containing target molecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) containing sulfonamide or sulfinate ester functional groups.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides where the sulfinic acid moiety contributes to biological activity.
• Peptide Mimetics & PROTACs: Serves as a versatile linker or functional handle in the design of peptide analogs and proteolysis-targeting chimeras (PROTACs).
• Material Science: Employed in the synthesis of specialty polymers and functional materials that require sulfur-based monomers.
• Chemical Biology Probes: Useful for creating activity-based probes or affinity labels to study enzyme function and protein interactions.
• Custom Synthesis & Contract Manufacturing: A valuable starting material for custom synthesis projects and scale-up campaigns in fine chemical production.
