α,α,β,β-Tetrachlorphenaethyl-phosphorimidyl-trichlorid, also known as TA-2, is a chemical compound with the formula C6Cl5PCl3NO. It is a derivative of phenylphosphonothioic dichloride, featuring a phosphorus atom bonded to four chlorine atoms, a nitrogen atom, and a phenyl group. α,α,β,β-Tetrachlorphenaethyl-phosphorimidyl-trichlorid is primarily used as a flame retardant and plasticizer, particularly in the production of polyvinyl chloride (PVC) and other polymers. Due to its high chlorine content, it imparts excellent flame resistance to materials. However, it has been identified as a potential environmental contaminant and is subject to regulatory restrictions in some regions due to its persistence and potential health risks.
The CAS Registry Mumber 38576-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,5,7 and 6 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 38576-52: (7*3)+(6*8)+(5*5)+(4*7)+(3*6)+(2*5)+(1*2)=152 152 % 10 = 2 So 38576-52-2 is a valid CAS Registry Number.
