Description

Propane-2-Sulfinamide CAS NO 19955-41-0 is a versatile chiral sulfinamide building block, primarily used as a key intermediate in asymmetric synthesis. Its core value lies in its ability to act as a highly effective chiral auxiliary or ligand, enabling the stereoselective construction of complex molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity intermediates for the development of active ingredients and advanced materials.

Application

• As a chiral auxiliary in the asymmetric synthesis of amines, amino acids, and amino alcohols.
• Key intermediate in the preparation of pharmaceutical active ingredients, particularly for central nervous system (CNS) and antiviral drugs.
• Building block for novel ligands used in asymmetric catalysis and transition metal complexes.
• Precursor in the synthesis of sulfoxides and other sulfur-containing fine chemicals.
• Research and development of new synthetic methodologies in academic and industrial laboratories.
• Intermediate for agrochemical products requiring specific stereochemistry for enhanced activity.
