Used primarily in the synthesis of organic compounds, 2-Ethylbenzenethiol serves as a key intermediate in the production of pharmaceuticals and agrochemicals. Its thiol group makes it valuable for creating sulfur-containing molecules, which are often essential in drug development. Additionally, it is utilized in the manufacture of flavors and fragrances due to its distinct sulfurous aroma. In industrial applications, it acts as a corrosion inhibitor and stabilizer in certain chemical processes. Its reactivity also makes it suitable for research purposes in organic chemistry, particularly in studies involving thiol-ene reactions.
