Description

(S)-(-)-tert-Butyl tert-Butanethiosulfinate is a high-purity chiral thiosulfinate compound, a key intermediate in asymmetric synthesis and pharmaceutical research. Its value lies in its role as a versatile building block for introducing sulfur-containing stereocenters with high enantiomeric purity. This product is essential for R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality chiral auxiliaries and ligands.

Application

• Pharmaceutical Intermediate: Critical chiral building block for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly those containing sulfoxide or sulfinamide moieties.
• Asymmetric Synthesis Catalyst/Chiral Auxiliary: Used as a precursor for chiral sulfinylating agents and ligands in metal-catalyzed reactions to induce stereoselectivity.
• Agrochemical Research: Employed in the development of novel, enantioselective pesticides and herbicides where specific stereochemistry impacts biological activity.
• Material Science: Serves as a monomer or modifier in the synthesis of specialized polymers and advanced organic materials with tailored properties.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic chemistry, exploring new sulfur-based transformations.
