Description

Cyclopropanecarboxylic Acid, 1-Amino-2-Methyl-, Methyl Ester, (1S,2S)- (9Ci) is a high-purity, stereochemically defined chiral building block of significant interest in advanced organic synthesis. Its value lies in the rigid cyclopropane ring and functionalized ester group, which are key motifs for constructing complex molecular architectures with precise three-dimensional control. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, particularly for creating novel active ingredients and exploring structure-activity relationships.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the research and development of new active pharmaceutical ingredients (APIs), especially in antiviral, anticancer, and central nervous system (CNS) drug candidates.
• Agrochemical Synthesis: Used in the design and production of advanced pesticides and herbicides, where the cyclopropane moiety can enhance biological activity and environmental stability.
• Asymmetric Catalysis & Ligand Development: Serves as a precursor for chiral ligands or catalysts used in enantioselective synthesis to produce single-isomer compounds.
• Chemical Biology & Proteomics: Employed as a molecular scaffold or a reactive handle in the synthesis of probes for studying biological systems and protein interactions.
• Material Science Research: Investigated as a monomer or building block for novel polymers with unique mechanical or optical properties derived from the strained cyclopropane ring.
• Academic & Contract Research: A valuable reagent for methodological development in organic chemistry and for custom synthesis projects in contract research organizations (CROs).
