Product Description:

Methyl phenyl sulfoxide is an organosulfur compound characterized by a sulfinyl functional group (S=O) bonded to a methyl group and a phenyl group. It is a colorless to pale yellow liquid or low-melting solid with a melting point around 30-32°C. It is soluble in common organic solvents such as dichloromethane, chloroform, and acetone. This compound serves primarily as a versatile reagent and building block in organic synthesis. It is a key intermediate in the synthesis of various pharmaceuticals and biologically active molecules. Its sulfinyl group can act as a chiral auxiliary in asymmetric synthesis or be further transformed into other sulfur-containing functionalities like sulfones or thioethers. It is also used as a ligand in certain transition metal-catalyzed reactions and as a starting material for the preparation of other organosulfur compounds. Methyl phenyl sulfoxide should be handled with standard laboratory precautions. It may cause skin and eye irritation. It is stable under recommended storage conditions but should be kept away from strong oxidizing agents.
