Bis(4-chlorophenyl)sulfone is a chemical compound that has been shown to have high water permeability. It is a white solid at room temperature and can be dissolved in trifluoroacetic acid, hydrochloric acid, and sodium carbonate. Bis(4-chlorophenyl)sulfone has been shown to react with diphenyl sulfoxide, giving the corresponding sulfoxide. Bis(4-chlorophenyl)sulfone can undergo chemical reactions with other compounds to form new chemical compounds. This property makes it an excellent starting material for synthesizing new drugs. Bis(4-chlorophenyl)sulfone does not cause carcinogenesis in mice when administered orally for up to 12 months at concentrations of 1 ppm or higher.

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.
