Tris(2-chloro-1-methylethyl) phosphate (TCPP) - 13674-84-5

Key Functions: Flame - Fire Retardants

CASRN 13674-84-5 is a discrete organic chemical with a MW below 1,000. EPI v4.11 was used to estimate physical/chemical and environmental fate values in the absence of experimental data. Measured values from experimental studies were incorporated into the estimations. TCPP is produced by the reaction of phosphorus oxychloride and propylene oxide. The most abundant isomer in commercial products is the branched isomer, 2-Propanol, 1-chloro-, phosphate (3:1) (CASRN 13674-84-5) however other isomers are expected to be present and will be discussed in this report as appropriate when determining hazard designations. Chemical, fate, and toxicity data for the isomers represented by other CASRN were collected in the preparation of this AA and are listed below: 1-Propanol, 2-chloro-, 1,1`,1``-phosphate (3:1) (CASRN 6145-73-9); Phosphoric acid, bis(2-chloro-1-methylethyl) 2-chloropropyl ester (CASRN 76025-08-6) and Phosphoric acid, 2-chloro-1-methylethyl bis(2-chloropropyl) ester (CASRN 76649-15-5) (NAS, 2000).
