Tris(1,2-dioxyphenyl)cyclotriphosphazene is a cyclic phosphorus-containing compound with the chemical formula (C6H4O2)3P3N3. It is a white crystalline solid that is thermally stable and has a high melting point. tris(1,2-dioxyphenyl)cyclotriphosphazene is formed by the reaction of cyclotriphosphazene with three molecules of 1,2-dioxybenzene (o-phenylene glycol). The structure consists of a six-membered ring with alternating phosphorus and nitrogen atoms, and each phosphorus atom is bonded to two oxygen atoms from the dioxyphenyl groups. Tris(1,2-dioxyphenyl)cyclotriphosphazene is an important intermediate in the synthesis of various phosphorus-containing polymers and materials, such as flame retardants, adhesives, and specialty coatings, due to its unique properties and reactivity.
The CAS Registry Mumber 311-03-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,1 and 1 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 311-03: (5*3)+(4*1)+(3*1)+(2*0)+(1*3)=25 25 % 10 = 5 So 311-03-5 is a valid CAS Registry Number.
