Description

Cyclopentanone, 2-Benzoyl-3-Ethyl-, (2R,3S)-Rel- (9Ci) is a chiral, high-purity organic building block characterized by its cyclopentanone core substituted with benzoyl and ethyl groups. This compound matters as a sophisticated intermediate for the synthesis of complex molecules, offering precise stereochemistry critical for developing active pharmaceutical ingredients (APIs) and advanced materials. It is primarily needed by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for process development and scale-up activities.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel therapeutic agents, particularly for central nervous system (CNS) and anti-inflammatory drugs.
• Agrochemical Synthesis: Used in the production of advanced, stereospecific pesticides and herbicides where specific enantiomeric activity is required.
• Asymmetric Catalysis Research: Serves as a valuable substrate or ligand precursor in the development of new asymmetric catalytic reactions.
• Fine Chemical Manufacturing: Employed in the multistep synthesis of complex fragrance compounds, flavors, and other high-value specialty chemicals.
• Material Science Precursor: Potential use in the synthesis of organic semiconductors or liquid crystals due to its rigid, functionalized structure.
