 α-Toluenethiol (CAS NO.100-53-8) can be used as pesticides, pharmaceutical intermediates, it can be used as food flavor.

 α-Toluenethiol (CAS NO.100-53-8) is made by benzyl isothiourea hydrochloride plus alkaline hydrolysis, and then dilute sulfuric acid derived. The S-benzyl-isothiourea hydrochloride and 10% sodium hydroxide solution by adding the reactor, using direct fire heating reflux 2h hydrolysis. And then cooled then diluted sulfuric acid acidification, extracted with diethyl ether, ethyl ether extract dried with anhydrous sodium sulfate, filter out the drying agent, recycling ether, the residue vacuum distillation, collecting the boiling point 98-108 ℃ (2.67kPa), the fraction shall be finished.

Reported in EPA TSCA Inventory.

Poison by inhalation and intraperitoneal routes. Moderately toxic by ingestion. An eye irritant. Questionable carcinogen with experimental tumorigenic data. Flammable when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, use foam, CO₂, dry chemical, water spray, mist, fog. When heated to decomposition and on contact with acid or acid fumes it emits highly toxic fumes of SO_x. See also SULFIDES and MERCAPTANS.
