Tripropyl-aethyl-phosphonium S-methyl-O-<2,4,5-trichlorophenyl>-thiophosphat is a complex organic compound with the chemical formula C15H24Cl3OPS. It is a phosphonium salt, which is a type of quaternary ammonium salt containing a phosphorus atom. The compound consists of a tripropylethylphosphonium cation and a S-methyl-O-(2,4,5-trichlorophenyl)-thiophosphat anion. The 2,4,5-trichlorophenyl group is a substituted phenyl ring with three chlorine atoms attached at the 2, 4, and 5 positions. Tripropyl-aethyl-phosphonium S-methyl-O-<2,4,5-trichlor-phenyl>-thiophosphat is known for its potential use as a flame retardant, particularly in plastics and textiles, due to its ability to interrupt the combustion process. It is also recognized for its effectiveness in reducing the flammability of materials without significantly affecting their physical properties.
The CAS Registry Mumber 7016-85-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,1 and 6 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 7016-85: (6*7)+(5*0)+(4*1)+(3*6)+(2*8)+(1*5)=85 85 % 10 = 5 So 7016-85-5 is a valid CAS Registry Number.
