Phosphine is the common name for phosphorus hydride (PH3), also known by the IUPAC name phosphane. It is a colorless, flammable gas with a boiling point of −88 °C at standard pressure. Pure phosphine is odorless, but "technical grade" phosphine has a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphine (P2H4).
