'''Arsine''' ([[IUPAC]] name: '''arsane''') is an [[inorganic compound]] with the [[Chemical formula|formula]] [[arsenic|As]][[hydrogen|H]]<sub>3</sub>. This flammable, [[pyrophoric]], and highly toxic [[pnictogen hydride]] gas is one of the simplest compounds of [[arsenic]].<ref name="Holleman"/> Despite its lethality, it finds some applications in the semiconductor industry and for the synthesis of [[organoarsenic compound]]s. The term ''arsine'' is commonly used to describe a class of [[organoarsenic]] compounds of the formula AsH<sub>3−''x''</sub>R<sub>''x''</sub>, where R = [[Aryl group|aryl]] or [[Alkyl group|alkyl]]. For example, As(C<sub>6</sub>H<sub>5</sub>)<sub>3</sub>, called [[triphenylarsine]], is referred to as "an arsine".
