Description

4-Cyclohexene-1,3-Dicarboxylic Acid, trans- (9Ci) CAS NO 71195-33-0 is a high-purity, unsaturated dicarboxylic acid derivative that serves as a versatile and valuable synthetic intermediate in advanced organic chemistry. Its rigid, functionalized cyclohexene core makes it an essential building block for creating complex molecular architectures with precise stereochemistry. This compound is primarily sought by research chemists and process development scientists in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring controlled functionalization and ring-opening reactions.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly those containing functionalized cyclohexane or cyclohexene rings.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators where its dicarboxylic acid functionality allows for further derivatization.
• Polymer Chemistry: Acts as a monomer or co-monomer for producing specialty polyesters, polyamides, and other polymers with tailored thermal and mechanical properties.
• Ligand and Catalyst Development: The carboxylate groups serve as excellent coordination sites for constructing metal-organic frameworks (MOFs) and homogeneous catalysts.
• Organic Synthesis Research: Employed in Diels-Alder reactions, hydrogenation studies, and as a precursor for other fine chemicals in academic and industrial R&D laboratories.
• Material Science: Investigated for creating novel organic semiconductors and liquid crystal compounds due to its planar, conjugated potential.
