Description

(1R,4S)-Methyl 4-Aminocyclopent-2-Enecarboxylate (Hydrochloride) is a high-purity, chiral building block of significant importance in advanced organic synthesis. Its value lies in its rigid, functionalized cyclopentene scaffold, which serves as a key intermediate for constructing complex molecules with precise stereochemistry. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, particularly for the synthesis of novel active pharmaceutical ingredients (APIs) and other fine chemicals.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the development of new drug candidates, especially in central nervous system (CNS) and antiviral therapeutic areas.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides where specific stereochemistry is required for biological activity.
• Asymmetric Catalysis Research: Serves as a precursor or ligand in the development of new chiral catalysts for stereoselective reactions.
• Fine Chemical Production: Employed in the multi-step synthesis of complex, high-value specialty chemicals and flavors/fragrances.
• Academic & R&D Laboratories: A valuable tool for methodological studies in organic chemistry, particularly in ring-forming and functionalization reactions.
