WebPhosphine is a super- toxic gas with a probable oral lethal dose of 5 mg/kg or 7 drops for a 150 pound person. 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. (EPA, 1998) Reactivity Profile PHOSPHINE is a reducing agent. WebOrganophosphines are organophosphorus compounds with the formula PR n H 3−n, where R is an organic substituent. These compounds can be classified according to the value of n: primary phosphines ( n = 1), secondary phosphines ( n = 2), tertiary phosphines ( n = 3). All adopt pyramidal structures. [1]

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 (
