DI-PHENYL SULPHONE (DPS) CAS No. 127-63-9 About

Diphenyl sulfone (commonly known as Diphenyl sulphone, Phenyl sulfone, or 1,1-Sulfonylbisbenzene) is an aromatic sulfone compound consisting of two phenyl groups attached to a sulfonyl functional group (SO). It typically appears as a white crystalline solid with high thermal stability and good chemical resistance, making it useful in various synthetic processes. Diphenyl sulfone is widely used as a solvent and intermediate in organic synthesis and polymer chemistry. In laboratory and industrial applications, it is commonly utilized in the manufacture of high-performance polymers such as polyethersulfones and polysulfones, as well as in the production of pharmaceuticals, specialty chemicals, and heat-resistant materials used in advanced engineering industries.
