Description

Cyclopentanecarboxaldehyde, 2,2-Dimethyl-1-(2-Nitroethyl)-, (1S)- (9Ci) is a high-purity chiral building block featuring a cyclopentane core, a nitroethyl group, and an aldehyde functionality. This compound matters for its role as a key synthetic intermediate in the production 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 constructing novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Serves as a crucial chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and cardiovascular drugs.
• Agrochemical Synthesis: Used in the research and development of novel pesticides and herbicides, where its structural complexity can contribute to new modes of action.
• Asymmetric Catalysis Research: Employed as a substrate or ligand precursor in the development of new asymmetric catalytic reactions due to its rigid, stereodefined structure.
• Fine Chemical Production: Acts as a building block for the manufacture of specialty chemicals, flavors, and fragrances requiring specific stereochemistry.
• Material Science Research: Investigated as a monomer or precursor for synthesizing novel polymers with specific optical or mechanical properties.
