Description

Benzenesulfonamide, 4-(1-Aminoethyl)-, (R)- (9Ci) is a chiral benzenesulfonamide derivative characterized by its specific stereochemistry at the aminoethyl side chain. This compound matters as a valuable chiral building block and intermediate in the synthesis of more complex molecules, particularly in the pharmaceutical sector. It is primarily needed by research institutions and chemical manufacturers specializing in the development of active pharmaceutical ingredients (APIs), agrochemicals, and specialty fine chemicals where stereochemical purity is critical.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of novel drug candidates, especially for central nervous system (CNS) and cardiovascular targets.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides, where the specific (R)-enantiomer can be crucial for biological activity and environmental safety.
• Catalyst and Ligand Development: Acts as a precursor for the synthesis of chiral ligands used in asymmetric catalysis to create enantiomerically pure compounds.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, dyes, and advanced materials that require sulfonamide functionality with specific chirality.
• Biochemical Research: Utilized as a standard or reagent in biochemical assays and studies involving enzyme inhibition or receptor binding where stereoselectivity is a factor.
