4,4′-Dichlorodiphenyl sulfone (DCDPS) is an organic compound with the formula (ClC 6 H 4) 2 SO 2. Classified as a sulfone , [ 1 ] this white solid is most commonly used as a precursor to polymers that are rigid and temperature-resistant such as PES or Udel.
DCDPS is the precursor to polymers known as Udel (from bisphenol A), PES, and Radel R. Udel is a high-performance amorphous sulfone polymer that can molded into a variety of different shapes. It is both rigid and temperature-resistant, and has applications in everything from plumbing pipes, to printer cartridges, to automobile fuses.
Diphenyl sulfone is an organosulfur compound with the formula (C 6 H 5) 2 SO 2.It is a white solid that is soluble in organic solvents.It is used as a high temperature solvent. Such high temperature solvents are useful for processing highly rigid polymers, e.g., PEEK, which only dissolve in very hot solve

Dapsone, also known as 4,4'-sulfonyldianiline (SDA) or diaminodiphenyl sulfone (DDS), [3] is an antibiotic commonly used in combination with rifampicin and clofazimine for the treatment of leprosy. [4]
A sulfone. It consists of a sulfonyl group bonded with two organic substituents. In organosulfur chemistry , a sulfonyl group is either a functional group found primarily in sulfones , or a substituent obtained from a sulfonic acid by the removal of the hydroxyl group, similarly to acyl groups .
Diphenyl sulfide and its analogues can also be produced by coupling reactions using metal catalysts. [5] It can also be prepared by reduction of diphenyl sulfone. [6] Diphenyl sulfide is a product of the photodegradation of the fungicide edifenphos. [7] Diphenyl sulfide is a precursor to triaryl sulfonium salts, which are used as photoinitiators.
