Description

Cyclopentanecarboxylic Acid, 2-Amino-4-Methyl-, (1R,2S)-Rel-[Partial]- (9Ci) is a high-purity, stereochemically defined chiral building block of significant interest in advanced organic synthesis. Its value lies in its functionalized cyclopentane scaffold, which serves as a key precursor for constructing complex molecules with precise three-dimensional architecture. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, particularly for the synthesis of novel active ingredients, chiral ligands, and other fine chemicals where stereochemical control is paramount.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the research and development of new active pharmaceutical ingredients (APIs), especially those targeting central nervous system (CNS) disorders, metabolic diseases, and anti-infectives.
• Agrochemical Synthesis: Used in the creation of advanced, stereoselective herbicides, fungicides, and insecticides, where the specific spatial orientation of the molecule can enhance efficacy and reduce environmental impact.
• Chiral Catalyst & Ligand Development: Serves as a foundational structure for designing novel asymmetric catalysts and ligands used in enantioselective synthesis to produce single-isomer compounds.
• Fine Chemical & Specialty Material Production: Employed in the synthesis of complex fragrances, flavors, and advanced materials that require a specific chiral cyclopentane core.
• Academic & Contract Research: A valuable reagent for universities and CROs (Contract Research Organizations) conducting methodological studies in stereochemistry and total synthesis of natural products.
