Trioctylphosphine Oxide CAS 78-50-2

Trioctylphosphine Oxide is a white waxy solid or colourless viscous liquid (depending on purity).Mainly used as metal extractant (e.g. uranium, rare earth separation), organic synthesis catalyst and precursor of photoelectric materials, its high coordination ability and thermal stability are outstanding.It needs to be kept away from light and moisture, it is irritating to skin and requires protection when operating.
