1,4-Cyclohexanedicarboxybic acid Molecular formula: C8H12O4 Structural formula: Molecular weight: 172.18 CAS: 1076-97-7(cis-trans Mixture),619-82-7(trans) 619-81-8(cis) Properties of Pure Products: The cis-trans mixture exists as white crystals, soluble in such organic solvents as ethanol, aceton, and chloroform with the solubility of 10%, and melting point of 164-167°C. The trans-1,4-cyclohexanedicarboxybic acid exists as white prismatic crystals with less water solubility than the cis-1,4-cyclohexanedicarboxybic acid and its melting point being over 300°C. The cis-1,4-cyclohexanedicarboxybic acid exists as white leaf-blade crystals with considerable water solubility and the melting point of 170-171°C. Uses: It is used as synthetic drug for digestive ulcers in medicine, and as modified monomers for polyester resin, to improve its etiolation, and improve its flexibility without changing its hardness. Packing : In cardboard pails lined with plastic bags with the net content of 25 kg per pail.
