p-Toluenethiol Usage And Synthesis

Chemical Properties

White or colorless solid melt

Uses

p-Thiocresol is used as a pharmaceutical intermediate.

Synthesis Reference(s)

Tetrahedron Letters, 21, p. 1235, 1980 DOI: 10.1016/S0040-4039(00)71380-3

Safety Profile

Poison by intraperitoneal route. A flammable liquid. When heated to decomposition it emits toxic fumes of SOx. See also a- TOLUENETHIOL and MERCAPTANS.

Purification Methods

Crystallise the thiol from pet ether (b 40-70o). The 2,4-dinitrophenyl thioether has m 103o (from EtOH), and the 2,4-dinitrophenyl sulfone has m 190o (from EtOH). [Beilstein 6 IV 2153.]
