- As a source of phosphorus and as a ligand for the synthesis of transition metal phosphide nanoparticles via heating-up process.
- To convert alcohols to alkyl halides.
- As a peptide coupling agent.
- As a low-temperature source of singlet oxygen after forming an adduct with ozone.
- To synthesize bromotriphenoxyphosphonium bromide, a brominating agent, by reacting with bromine.
| | 空気と水の反応 | Insoluble in water. | | 反応プロフィール | Organophosphates, such as Triphenyl phosphite, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. | | 健康ハザード | Triphenyl phosphite (TPP) is a
skin irritant and sensitizer in humans and is
neurotoxic in laboratory animals.Systemic effects have not been reported in
humans. | | 安全性プロファイル | Poison by
intraperitoneal and subcutaneous routes.
Moderately toxic by ingestion. An
experimental eye and severe human skin
irritant. Combustible when exposed to heat
or flame. To fight fire, use CO2, mist, dry
chemical. When heated to decomposition it
emits toxic fumes of POx. See also
