Description

Cyclopropanecarboxylic Acid, 2-Cyano-1-Methyl-, Ethyl 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 pharmaceutical, agrochemical, and fine chemical industries seeking to introduce the unique steric and electronic properties of the cis-substituted cyclopropane moiety into target compounds.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring a cis-cyclopropyl scaffold for biological activity.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, insecticides, and fungicides where the cyclopropane structure can enhance stability and efficacy.
• Ligand and Catalyst Development: Employed in the creation of specialized chiral ligands or organocatalysts for asymmetric synthesis applications.
• Material Science Research: Acts as a monomer or functionalizing agent in the development of advanced polymers with tailored properties.
• Academic & Industrial R&D: A valuable reagent for methodological studies and exploring new chemical spaces in synthetic organic chemistry.
