Tris-<4-nitro-phenoxy>-phosphazosulfonylmethyl, also known as TNPP, is a complex organic compound with the chemical formula C18H15N3O9PS3. It is a yellow crystalline solid that is soluble in water and various organic solvents. TNPP is primarily used as a flame retardant and a stabilizer in the production of polyurethane foams, as it helps to prevent the foam from catching fire and degrading over time. The compound is also known for its ability to inhibit the growth of microorganisms, making it a useful additive in various industrial applications. Due to its chemical structure, TNPP contains multiple nitro groups, which contribute to its flame-retardant properties, and a phosphorus atom, which enhances its thermal stability. However, it is important to note that the use of TNPP and other flame retardants is subject to regulatory considerations due to potential environmental and health concerns.
The CAS Registry Mumber 94302-07-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,3,0 and 2 respectively; the second part has 2 digits, 0 and 7 respectively. Calculate Digit Verification of CAS Registry Number 94302-07: (7*9)+(6*4)+(5*3)+(4*0)+(3*2)+(2*0)+(1*7)=115 115 % 10 = 5 So 94302-07-5 is a valid CAS Registry Number.
