Tris(α-hydroxy-β,β,β-trichloroethyl)phosphine is a complex organophosphorus compound with the chemical formula C6H9Cl6O3P. It is a colorless, viscous liquid that is soluble in organic solvents. tris(α-hydroxy-β,β,β-trichloroethyl)phosphine is characterized by its unique structure, featuring a central phosphorus atom bonded to three α-hydroxy-β,β,β-trichloroethyl groups. The presence of hydroxyl and chloro substituents on the ethyl groups contributes to its chemical reactivity and potential applications. Tris(α-hydroxy-β,β,β-trichloroethyl)phosphine is primarily used as a flame retardant, particularly in plastics and textiles, due to its ability to char materials and prevent the spread of flames. It is also employed as a stabilizing agent in various chemical processes. However, due to its potential health and environmental risks, its use is subject to strict regulations.
The CAS Registry Mumber 17977-57-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,7 and 7 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 17977-57: (7*1)+(6*7)+(5*9)+(4*7)+(3*7)+(2*5)+(1*7)=160 160 % 10 = 0 So 17977-57-0 is a valid CAS Registry Number.
