Product Description:

Diphenyl sulfoxide is an organosulfur compound characterized by the chemical formula (C6H5)2SO. It is a white to off-white crystalline solid with a melting point of approximately 70-73 °C. As a sulfoxide, it features a sulfur atom bonded to two phenyl groups and one oxygen atom via a double bond, giving it a polar nature. Its primary role is as a versatile reagent and building block in organic synthesis. It is commonly used as a ligand in transition metal-catalyzed reactions and as a precursor for generating other sulfur-containing compounds. For instance, it can be reduced to diphenyl sulfide or oxidized to diphenyl sulfone. It also serves as a polar, aprotic solvent for specific reactions and finds utility in the synthesis of pharmaceuticals and fine chemicals, often as an intermediate. Handling requires standard laboratory precautions. It is generally stable under recommended storage conditions but should be kept away from strong oxidizing agents.
