Tris(1,3-dichloro-2-propyl)phosphate
Tris(1,3-dichloroisopropyl)phosphate (TDCPP) is a chlorinated organophosphate. Organophosphate chemicals have a wide variety of applications and are used as flame retardants, pesticides, plasticizers, and nerve gases. TDCPP is structurally similar to several other organophosphate flame retardants, such as tris(2-chloroethyl) phosphate (TCEP) and tris(chloropropyl)phosphate (TCPP). TDCPP and these other chlorinated organophosphate flame retardants are all sometimes referred to as "chlorinated tris". Manufacture Uses Flame retardant Until the late 1970s, TDCPP was used as a flame retardant in children’s pajamas in compliance with the U.S. Flammable Fabrics Act of 1953. This use was discontinued after children wearing fabrics treated with a very similar compound, tris(2,3-dibromopropyl) phosphate, were found to have mutagenic byproducts in their urine. Following the 2005 phase-out of PentaBDE in the United States, TDCPP became one of the primary flame retardants used in flexible polyurethane foam used in a wide variety of consumer products, including automobiles, upholstered furniture, and some baby products. TDCPP can also be used in rigid polyurethane foam boards used for building insulation. In 2011 it was reported that TDCPP was found in about a third of tested baby products. Some fabrics used in camping equipment are also treated with TDCPP to meet CPAI-84, a standard established by
