Description

Cyclohexanecarboxylic Acid, 2-(Chlorocarbonyl)-, Methyl Ester, (1R,2S)-Rel- (9Ci) is a high-purity chiral building block of significant importance in advanced organic synthesis. Its value lies in its dual functional groups—the acid chloride and ester moieties—which enable precise, sequential derivatization under controlled conditions. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries who require enantiomerically enriched intermediates for developing active pharmaceutical ingredients (APIs) and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex, biologically active molecules and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Ligand and Catalyst Development: Serves as a precursor for creating novel chiral ligands and organocatalysts used in asymmetric synthesis.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances requiring specific stereochemistry.
• Academic and R&D: A valuable reagent for methodological development in organic chemistry and medicinal chemistry research programs.
