Application

Phenylphosphonic dichloride (PPDC) is an organophosphorus compound with flame-retardant properties.
It can be used:
  • In the synthesis of PBPP (3,9-diphenyl-3,9-dioxa-2,4,8,10-tetraoxa-3,9-diphosphaspiro-5,5-undecane), another organo-phosphorus flame retardant.
  • As a reactant in the synthesis of perfluoroalkyl(phenyl)phosphinic acids from perfluoroalkyl Grignard reagents.
  • As a starting material for the synthesis of benzoxazine monomer containing phenylphosphine oxide which can be polymerized via ring-opening polymerization.
  • As a chlorinating agent for the conversion of thienopyrimidinedione into 4,6-dichlorothienopyrimidine.
