METHYL PHENYL SULFOXIDE Usage And Synthesis

Chemical Properties

white crystalline low melting mass

Uses

Methyl phenyl sulfoxide has been used in the synthesis of:

• isotopically labelled 1, 3-dithiane, a useful labeled synthon
• nelfinavir, potent HIV-protease inhibitor
• sulfoximines and in studies on solvent-water partitioning

Definition

ChEBI: (methylsulfinyl)benzene is a sulfoxide resulting from the formal oxidation of the sulfur atom of thioanisole. It is a sulfoxide and a member of benzenes. It is functionally related to a thioanisole.
