tris246trichlorophenylphosphate
Tris(2,4,6-trichlorophenyl) phosphite, often abbreviated as Tris(2,4,6-TCP) phosphite or TTP, is a chemical compound used primarily as a flame retardant. It is a white crystalline solid with a high melting point and low solubility in water. Its chemical structure features a central phosphorus atom bonded to three oxygen atoms, each of which is in turn bonded to a 2,4,6-trichlorophenyl ring. This arrangement of chlorine atoms on the phenyl rings contributes to its flame-retardant properties by interfering with the combustion process.
TTP is incorporated into various polymeric materials, including plastics and textiles, to enhance their fire resistance.
