Trans-Cyclohexan-1,4-diol-bis-diphenylphosphat, also known as trans-1,4-Cyclohexanediamine diphenyl phosphate or DCHDP, is a chemical compound with the molecular formula C20H22O4P2. It is a colorless, crystalline solid that is soluble in organic solvents. DCHDP is primarily used as a flame retardant and plasticizer in various polymers, such as polyurethane, epoxy resins, and polyvinyl chloride. It is known for its high thermal stability, low toxicity, and excellent flame-retardant properties. The compound is synthesized by reacting trans-1,4-cyclohexanediamine with diphenyl phosphoric acid, resulting in a product that exhibits good compatibility with polymers and provides effective flame resistance.
The CAS Registry Mumber 4308-88-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,0 and 8 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4308-88: (6*4)+(5*3)+(4*0)+(3*8)+(2*8)+(1*8)=87 87 % 10 = 7 So 4308-88-7 is a valid CAS Registry Number.
