What is a Ethanethiol (C₂H₅SH) ?

Ethanethiol (C₂H₅SH) is an organic compound classified as a thiol, containing sulfur. It is a colorless or pale yellow liquid with a strong, unpleasant odor, often likened to the smell of rotten cabbage or garlic. Ethanethiol is commonly used as an odorant added to natural gas to help detect leaks, as the gas itself is odorless.

Chemically, ethanethiol is used in the synthesis of various compounds, including pharmaceuticals, agrochemicals, fragrances, and plastics. As a sulfur-containing compound, ethanethiol serves as a reducing agent and is also used as a catalyst in certain reactions.

Industrially, ethanethiol is important in gas systems and chemical synthesis. Due to its high volatility and corrosive nature, careful handling and storage are required.
