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.]
