Overview of 2-Propanethiol

2-Propanethiol (CAS No. 75-33-2) is a transparent yellow liquid that is colourless and pale, with a distinct, skunk-like smell that is unpleasant. It's characteristic of low molecular-weight thiols (mercaptans). It is a volatile and chemical sulfur that is flammable, and that is used in industrial, chemical research and other sectors. It's a little liquid in water, but it readily dissolves in organic solvents like ethers and alcohols, because of its strong smell, which also serves to disguise the detection of gas leaks.

Applications of 2-Propanethiol

Chemical Industry

Serves as an intermediate in the synthesis of organic sulfur compounds.

Used in the production of agrochemicals and speciality chemicals.

Related chemicals for synthesis: Dimethyl Trisulfide, Methyl Isobutyl Ketone

Gas Industry

Added in trace amounts as an odorant in natural gas and LPG for leak detection because of its pungent smell.

Pharmaceuticals & R&D

Applied as a laboratory reagent in organic synthesis. Studied as a building block in thiol-based compounds and pharmaceutical research.

Specialty Applications

Sometimes used in flavour and fragrance R&D in highly diluted concentrations for sulfuric, roasted, or savoury notes, though its direct use is limited due to strong odour intensity.

Safety & Handling Guidelines

  • Handle with protective gloves, goggles, and suitable clothing to prevent skin and eye contact.

  • Use only in well-ventilated areas or under fume hoods to avoid inhalation of vapours.

  • Store in tightly closed containers in a cool, dry place away from heat, sparks, flames, and oxidising agents.

  • Extremely flammable — keep away from ignition sources.

  • Wash thoroughly after handling; prolonged exposure should be avoided.

  • Refer to the full MSDS for toxicological details and first-aid measures.
