Description

Cyclopentanecarbonitrile, 2-Acetyl-1-Methyl- (7Ci) is a specialized organic nitrile building block featuring a cyclopentane ring substituted with acetyl and methyl groups. This compound matters as a versatile chiral intermediate for the synthesis of complex molecules, particularly in the pharmaceutical sector where its unique structure enables the construction of specific stereocenters. It is primarily needed by research and development chemists and process scale-up teams in the fine chemical and pharmaceutical industries for creating active pharmaceutical ingredients (APIs) and advanced agrochemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and anti-inflammatory therapeutic areas.
• Agrochemical Synthesis: Used in the research and development of advanced pesticides and herbicides, leveraging its nitrile functionality for further chemical transformations.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Fine Chemical Production: Employed in custom synthesis and contract manufacturing for producing high-value, low-volume specialty chemicals.
• Academic and Industrial Research: A valuable reagent for methodological studies in organic synthesis, including ring-forming reactions and functional group manipulations.
