Specification

The Dichlorophenylphosphine, with the CAS registry number 644-97-3, is also known as Phenyldichlorophosphine. It belongs to the product categories of Chlorophosphines; Pharmaceutical Intermediates; Ligand; Organophosphine halide. Its EINECS number is 211-425-8. This chemical's molecular formula is C₆H₅Cl₂P and molecular weight is 178.98. What's more, its systematic name is Phenylphosphonous dichloride. This colourless viscous liquid is commonly used in the synthesis of phosphine ligands. Dichlorophenylphosphine is commercially available. It may be prepared by a electrophilic substitution of benzene by phosphorus trichloride, catalyzed by aluminium chloride. This chemical should be sealed and stored in a cool and dry place. Moreover, it should be protected from oxides, acids, heat and fire.
