Tris-2-pyridyl phosphate (TCPP) is a phosphorus-based flame retardant chemical compound, with the chemical formula C12H9N3O6P. It is widely used in various applications, including plastics, textiles, and building materials, to enhance fire resistance and reduce the risk of fire-related hazards. TCPP works by releasing phosphorus-containing compounds when exposed to heat, which interrupts the combustion process and slows down the spread of flames. However, concerns have been raised about its potential environmental and health impacts, as it can leach into the environment and accumulate in living organisms, posing risks to both ecosystems and human health. As a result, there is ongoing research and debate about the safety and regulation of TCPP and other flame retardant chemicals.
The CAS Registry Mumber 1659-23-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 9 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1659-23: (6*1)+(5*6)+(4*5)+(3*9)+(2*2)+(1*3)=90 90 % 10 = 0 So 1659-23-0 is a valid CAS Registry Number.
