Description

Cyclohexanecarboxylic Acid, 4-Acetyl-, trans- (9Ci) is a specialized, high-purity organic compound featuring a trans-configured cyclohexane ring substituted with both acetyl and carboxylic acid functional groups. This specific stereochemistry and functional group combination make it a valuable and versatile chiral building block for advanced organic synthesis. It is primarily sought after by research chemists and process development scientists in the pharmaceutical and fine chemical industries who require precise molecular scaffolds to synthesize complex, biologically active molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly in areas requiring stereochemical control.
• Asymmetric Synthesis: Serves as a precursor or starting material for catalysts and ligands used in enantioselective chemical transformations.
• Fine Chemical Production: Used in the multi-step synthesis of complex agrochemicals, flavors, fragrances, and specialty polymers.
• Academic & Industrial Research: A critical reagent for methodological studies in organic chemistry, including new reaction development and natural product synthesis.
• Material Science: Potential monomer or modifying agent for creating polymers with specific thermal or mechanical properties derived from the rigid cyclohexane structure.
