Pharmaceutical Materials

trans-DL-1,2-Cyclopentanedicarboxylic acid (CPDA) is a colorless crystalline solid with the molecular formula C₇H₁₀O₄ and a molecular weight of 158.15 g/mol. It is widely recognized as a key intermediate in the synthesis of nylon 6,10, a high-performance polymer used in fibers, plastics, and engineering materials. CPDA is also utilized in pharmaceuticals, serving as a precursor for drugs like gliclazide. The compound is typically prepared via oxidation of octanol using cobalt or manganese catalysts. It exhibits high melting point (163–165°C), strong corrosion resistance, and solubility in organic solvents such as DMSO and methanol. Due to its versatility, CPDA plays a critical role in both polymer chemistry and pharmaceutical synthesis.

Usage： Mainly used as Pharmaceutical Intermediates.

Packaging and Shipping： 25KG/drum or as per buyer’s requirements.

Storage: Storage in ventilated low temperature dry warehouse; Keep container closed and separately from open flame and heat source.
