Bis(4-chlorophenyl) sulfone is used as a precursor to prepare 4,4'-diamino-diphenyl sulfone and polysulfone plastics. It is also used to prepare rigid and temperature resistant polymers such as PES or Udel through polymerization with bisphenol-A and bisphenol-S. Further, the udel polymer finds applications in plumbing pipes, printer cartridges and automobile fuses.
4,4’Dichlorodiphenyl Sulfone is an impurity of Dapson (D193250), an antibacterial used in the treatment of dermatitis herpetiformis.
Crystals or off-white powder.
4,4'-Dichlorodiphenyl sulfone is incompatible with strong oxidizers.
Flash point data for 4,4'-Dichlorodiphenyl sulfone are not available; however, 4,4'-Dichlorodiphenyl sulfone is probably combustible.
Flammability and Explosibility
Non flammable
Mildly toxic by ingestion. When heated to decomposition it emitsvery toxic fumes of Cl- and SOx.
