Description

Cyclopentanecarboxylic Acid, 3-Methyl-, (1R-Trans)- (9Ci) is a high-purity chiral building block of significant interest in advanced organic synthesis. This compound matters as a key intermediate for constructing complex molecules with defined stereochemistry, which is critical for developing active pharmaceutical ingredients (APIs) and specialty agrochemicals. It is primarily needed by research and development chemists, process development scientists, and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries seeking to introduce the cyclopentane scaffold with precise stereocontrol.

Application

• Pharmaceutical Intermediate: Serves as a crucial chiral synthon in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, cardiovascular diseases, and anti-inflammatory agents.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides where the specific stereochemistry of the cyclopentane ring influences biological activity and environmental profile.
• Fine Chemical Production: Acts as a building block for creating complex fragrance molecules, flavors, and other high-value specialty chemicals requiring defined three-dimensional structure.
• Asymmetric Catalysis Research: Employed as a substrate or ligand precursor in academic and industrial research focused on developing new stereoselective synthetic methodologies.
• Material Science Precursor: Potential use in the synthesis of specialized monomers for polymers with unique thermal or mechanical properties derived from the strained cyclopentane core.
