Description

2-Propanone, 1-[(1R,2R)-2-Methylcyclopentyl]-, Rel- (9Ci) is a chiral, optically active ketone derivative of 2-propanone (acetone) featuring a methylcyclopentyl substituent. This compound is valued as a specialized chiral building block and intermediate in advanced organic synthesis, where its defined stereochemistry is critical for creating molecules with specific three-dimensional structures. It is primarily needed by research and development laboratories, as well as process chemists in the pharmaceutical and agrochemical industries, for applications in asymmetric synthesis and the development of active pharmaceutical ingredients (APIs).

Application

• Chiral Intermediate in Pharmaceutical Synthesis: Serves as a key building block for the synthesis of complex, stereochemically defined active pharmaceutical ingredients (APIs).
• Agrochemical Research & Development: Used in the creation of novel pesticides and herbicides where specific stereoisomers exhibit enhanced biological activity.
• Asymmetric Catalysis & Ligand Development: Acts as a precursor or framework for developing chiral ligands and catalysts used in enantioselective reactions.
• Fine Chemical and Specialty Material Production: Employed in the synthesis of advanced materials, flavors, and fragrances requiring precise molecular architecture.
• Academic and Industrial R&D: Utilized in research laboratories for methodological studies in organic chemistry and the exploration of new synthetic pathways.
