4,4'-Dichlorodiphenyl sulfone Usage And Synthesis

Chemical Properties

off-white crystals or powder

Uses

4,4’Dichlorodiphenyl Sulfone is an impurity of Dapson (D193250), an antibacterial used in the treatment of dermatitis herpetiformis.

Uses

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.

General Description

Crystals or off-white powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

4,4'-Dichlorodiphenyl sulfone is incompatible with strong oxidizers.

Fire Hazard

Flash point data for 4,4'-Dichlorodiphenyl sulfone are not available; however, 4,4'-Dichlorodiphenyl sulfone is probably combustible.

Flammability and Explosibility

Non flammable

Safety Profile

Mildly toxic by ingestion. When heated to decomposition it emitsvery toxic fumes of Cl- and SOx.
