Description

Cyclopentaneacetonitrile, 2-Methoxy-3-Oxo-, (1R,2S)-Rel- (9Ci) is a chiral, high-purity chemical intermediate characterized by its cyclopentane backbone and functionalized acetonitrile group. This compound matters for its role as a sophisticated building block in the synthesis of complex, biologically active molecules, where its defined stereochemistry is critical for efficacy. It is primarily needed by research and development teams in the pharmaceutical and agrochemical industries for creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and metabolic disorder targets.
• Agrochemical Synthesis: Used in the production of advanced, stereospecific pesticides and herbicides where specific chirality enhances biological activity and reduces environmental impact.
• Asymmetric Catalysis Research: Serves as a valuable substrate or ligand precursor in the development of new catalytic systems for stereoselective synthesis.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances that require high stereochemical purity.
• Academic & Contract Research: Utilized in university and CRO laboratories for methodological studies in organic and medicinal chemistry.
