Description

Cyclopentanecarboxylic Acid, 2-Hydroxy-, Methyl Ester, (1S,2S)- (9Ci) is a high-purity chiral building block of significant interest in advanced organic synthesis. This compound matters because its defined stereochemistry and functional groups make it a critical intermediate for constructing complex, biologically active molecules. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients, where stereochemical control is paramount for efficacy and safety.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the development of novel active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and metabolic disorder research.
• Agrochemical Synthesis: Used in the research and production of stereochemically defined pesticides and herbicides to enhance selectivity and reduce environmental impact.
• Asymmetric Catalysis Research: Serves as a substrate or ligand precursor in the development and testing of new chiral catalysts and synthetic methodologies.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals, flavors, and fragrances requiring high enantiomeric purity.
• Academic & Industrial R&D: A valuable tool for medicinal chemistry programs and process chemistry optimization in both university and corporate laboratory settings.
