Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide EC Number: 278-355-8 EC Name: Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide CAS Number: 75980-60-8 Molecular formula: C22H21O2P IUPAC Name: (diphenylphosphoroso)(2,4,6-trimethylphenyl)methanone Date of issue: 01/01/1980 Revision date: 08/31/2018 Supersedes: 10/24/2016 EN (English US) SDS ID: P-4643 1/10 As there is no suitable chemical to replace phosphine, it is essential to understand the mechanisms of phosphine toxicity to increase the effectiveness of resistance management. An air concentration of 3 ppm is safe for long term exposure, 500 ppm is lethal in 30 minutes, and a concentration of 1,000 ppm is lethal after a few breaths. It is a flammable gas that is usually pyrophoric (autoigniting in air). Triphenylphosphine oxide (CASRN 791-28-6) Superfund Health Risk Technical Support Center . Phosphine gas is a public health hazard. Cincinnati, OH 45268 Phosphine's immediate health hazards are that it is a toxic gas and may cause thermal burns. May produce highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. In agreement with its logPow of 3.1, only 12mg can be dissolved in one liter of water. Toxicological information Acute Toxicity Product Information Component Information Component LD50 Oral LD50 Dermal LC50 Inhalation Phosphine oxide, triphenyl- LD50 = 685 mg/kg ( Rat ) Not listed Not listed Toxicologically Synergistic Products No information available Office of Research and Development . National Center for Environmental Assessment . The selectivity profile of brigatinib over ALK has been shown to be due to the dimethyl phosphine oxide moiety only. U.S. Environmental Protection Agency . Provisional Peer Reviewed Toxicity Values for . The development of high-level resistance in insects now threatens its continued use. Animal owners and veterinary staff members must be cautious while inducing emesis, because they can be exposed to phosphine gas from the presence of zinc phosphide bait in the stomach contents after vomiting. Triphenylphosphine oxide Revision Date 18-Jan-2018 11. Phosphine is … Diphenyl(2,4,6-trimethylbenzoyl) phosphine oxide (TPO) is used as a key processing aid in form of a chemical photo-initiator for polymerisation in artificial nail systems, primarily in UV-curable one-component gel systems. The … The chemical features of brigatinib are responsible for its properties like expanded fluid solvency, diminished lipophilicity and decreased protein binding ( Huang et al., 2016 ). Phosphine is a super- toxic gas with a probable oral lethal dose of 5 mg/kg or 7 drops for a 150 pound person. Diphenyl(2,4,6 -trimethylbenzoyl)phosphine oxide is a powder with a molecular weight of 348 g/mol and a very low vapour pressure of 3x10e6Pa at 20 °C. It may form mixtures with air that do not autoignite, but are flammable or explosive.
