Description

Cyclopentanecarboxylic Acid, 2-Amino-, Methyl Ester, (1R,2R)-Rel- (9Ci) is a high-purity chiral building block of significant interest in advanced organic synthesis. This compound matters for its role as a key intermediate in the production of complex, stereochemically defined molecules, particularly in the pharmaceutical sector. It is primarily needed by R&D chemists and process development scientists working on active pharmaceutical ingredients (APIs), agrochemicals, and other fine chemicals where precise stereochemistry is critical for biological activity.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and cardiovascular therapeutic areas.
• Agrochemical Synthesis: Used in the research and development of enantiomerically pure pesticides and herbicides.
• Asymmetric Catalysis: Serves as a precursor or ligand in the development of chiral catalysts for stereoselective reactions.
• Fine Chemical Production: Employed in the manufacture of complex, high-value specialty chemicals requiring specific stereochemistry.
• Academic & Industrial Research: A valuable tool for methodological studies in organic synthesis and medicinal chemistry.
