126-72-7 Usage
Chemical Properties
TDBP is a thick, clear to yellowish liquid.
Odorless.
Uses
Different sources of media describe the Uses of 126-72-7 differently. You can refer to the following data:
1. 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.
2. Flame retardant for plastics and synthetic fibers. Formerly used in children's sleepwear.
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.
Check Digit Verification of cas no
The CAS Registry Mumber 126-72-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126-72:
(5*1)+(4*2)+(3*6)+(2*7)+(1*2)=47
47 % 10 = 7
So 126-72-7 is a valid CAS Registry Number.
InChI:InChI=1/C3H7Br2O4P/c4-1-3(5)2-9-10(6,7)8/h3H,1-2H2,(H2,6,7,8)/p-2
