Description

Cyclopropanecarboxylic Acid, 3-Cyano-2,2-Dimethyl-, Methyl Ester, cis- (9Ci) is a high-purity, specialized chemical intermediate featuring a functionalized cyclopropane ring system. This compound matters for its role as a critical building block in the synthesis of complex molecules, particularly in advanced pharmaceutical and agrochemical research. It is needed by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and crop protection industries seeking to incorporate its unique cis-configured, cyano-substituted cyclopropane scaffold into novel active ingredients.

Application

• Pharmaceutical Intermediate: A key synthon for the development of novel active pharmaceutical ingredients (APIs), particularly in medicinal chemistry programs targeting CNS and metabolic diseases.
• Agrochemical Synthesis: Serves as a precursor in the manufacture of advanced pesticides and herbicides, where the cyclopropane moiety can enhance biological activity.
• Fine Chemical Production: Used in custom synthesis and contract manufacturing for producing high-value, low-volume specialty chemicals.
• Research & Development: Employed in academic and industrial labs for methodological studies in organic synthesis, including ring-opening and functional group transformation reactions.
• Material Science Precursor: Potential use in the synthesis of monomers or ligands for advanced polymeric or coordination complex materials.
