Phosphonic diamide, N,N'-diphenyl-, also known as N,N'-diphenylphosphonic diamide, is an organic compound with the chemical formula C12H12N2OP. It is a white crystalline solid that is soluble in water and various organic solvents. Phosphonic diamide,N,N'-diphenyl- is primarily used as a flame retardant, particularly in the production of polyurethane foams, due to its ability to char and form a protective layer when exposed to heat. It is also known for its thermal stability and low toxicity, making it a preferred choice in certain applications over more hazardous flame retardants. The compound is synthesized through the reaction of diphenylamine with phosphorus trichloride, followed by hydrolysis. Its chemical structure features a central phosphorus atom bonded to two nitrogen atoms from the amide groups and two phenyl rings, which contribute to its stability and reactivity in various chemical processes.

4671-85-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4671-85-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,7 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4671-85:
(6*4)+(5*6)+(4*7)+(3*1)+(2*8)+(1*5)=106
106 % 10 = 6
So 4671-85-6 is a valid CAS Registry Number.
