=============================================================================
Purpose:
Mainly used as an intermediate in organic synthesis, it has applications in the synthesis of pharmaceuticals, fragrances, and electronic materials
As a solvent, it can be miscible with ethanol, ether, acetone, etc
In the food industry, as an edible spice (FEMA 3897), it is allowed to be used in baked goods, cold drinks, seasonings, etc., but the dosage is extremely low (0.1-5.0 mg/kg)
It is also used for scientific research, analytical reagents, and preparation of essence and fragrances

synthetic route
The industrial synthesis of isopropyl mercaptan usually uses 2-bromopropane (or isopropyl chloride) and thiourea as raw materials, which react to produce isopropyl isothiocyanate, and then hydrolyze to obtain it
Other common routes include:
Addition of propylene and hydrogen sulfide
Reduction of acetone and hydrogen sulfide under the action of catalyst
