Description

Cyclopentanemethanol, 2-(Acetyloxy)-, Acetate, (1R,2S)-Rel- (9Ci) is a high-purity chiral intermediate of significant importance in advanced organic synthesis. This compound matters because it provides a stereochemically defined building block for constructing complex molecules with precise three-dimensional architecture. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of active pharmaceutical ingredients (APIs), agrochemicals, and specialty fine chemicals where stereochemical control is critical. The product is supplied under strict quality control to ensure batch-to-batch consistency for demanding synthetic applications.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel Active Pharmaceutical Ingredients (APIs), particularly for central nervous system (CNS) and antiviral drug candidates.
• Agrochemical Synthesis: Used in the production of advanced, stereoselective pesticides and herbicides where specific enantiomers exhibit enhanced biological activity.
• Asymmetric Catalysis Ligand Precursor: Serves as a starting material for synthesizing chiral ligands and catalysts used in enantioselective transformations.
• Fine Chemical and Flavor/Fragrance Intermediate: Employed in the synthesis of complex, high-value aroma chemicals and specialty fine chemicals requiring specific stereochemistry.
• Academic and Industrial R&D: A valuable reagent for methodological development in organic chemistry, particularly in studies focused on stereocontrolled synthesis and ring systems.
• Material Science Research: Potential building block for chiral polymers or advanced organic materials with specific optical properties.
