Phosphine twa
Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4). With traces of P2H4 present, PH3 is spontaneously flammable in air ( WebFeb 15, 2010 · Phostoxin (phosine) is a restricted use chemical that carries a Danger signal word which alerts the user of the acute toxicity of the product being the highest on the scale.
