Tris(2,3-dibromopropyl)phosphate Chemical Properties,Usage,Production

Chemical Properties TDBP is a thick, clear to yellowish liquid. Odorless.
Uses Tris(2,3-dibromopropyl) Phosphate is a flame retardant that has previously shown to be a mutagen and carcinogen in experimental animals. Tris(2,3-dibromopropyl) Phosphate is widely used in pastics an d textiles.
Uses Flame retardant for plastics and synthetic fibers. Formerly used in children's sleepwear.
Definition ChEBI: Tris(2,3-dibromopropyl) phosphate is a trialkyl phosphate.
General Description Clear colorless to pale yellow viscous liquid.
Air & Water Reactions Insoluble in water.
Reactivity Profile TRIS(2,3-DIBROMOPROPYL)PHOSPHATE is stable at temperatures up to 392-482°F. Major decomposition begins at 586°F. Is hydrolyzed by acids and bases .
Hazard A carcinogen; use restricted.
Fire Hazard TRIS(2,3-DIBROMOPROPYL)PHOSPHATE is combustible.
Safety Profile Confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic, and teratogenic data. Poison by intraperitoneal route. Moderately toxic by ingestion, Experimental reproductive effects. Human mutation data reported. An eye and severe skin irritant. Can cause testicular atrophy and sterility. Once used as a flame retardant addtive to synthetic textiles and plastics, particularly in children's sleepwear. Use discontinued because it can be absorbed by human skin, or chewed or sucked off sleepwear by infants, May be flammable when exposed to heat or flame. When heated to decomposition it emits very toxic fumes of Brand POx.
Potential Exposure Tris-BP is used as a flame retardant additive for synthetic textiles and plastics. It was applied to fabrics used for children’s clothes (sleepwear in particular) with some used as a flame retardant in other materials, such as urethane foams. Commercial preparations of tris-BP can be obtained in two grades, viz, HV (high in volatiles) and LV (low in volatiles). A typical LV sample has been reported to contain the following impurities: 0.05% 1,2-dibromo-3-chloropropane (BrCH2CHBrCH2Cl); 0.05% 1,2,3-tribromopropane (BrCH2CHBrCH2Br); and Tris(2,3-dibromopropyl) Phosphate 3013 0.20% 2,3-dibromopropanol (BrCH2CHBrCH2OH). Use and expo sure has greatly decreased after a ruling by the Consumer Product Safety Commission in April 1977.
Carcinogenicity Tris(2,3-dibromopropyl) phosphate is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
Shipping UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Incompatibilities Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
Waste Disposal Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
