Used as an intermediate in organic synthesis, particularly in the production of fragrances and flavor compounds due to its aromatic, slightly sulfurous odor. It also serves in the development of certain pharmaceuticals where thiol-containing building blocks are required. Additionally, it can act as a ligand in metal complex formation for catalytic applications. Its ethyl-substituted aromatic thiol structure makes it useful in modifying surface properties in materials science, especially in self-assembled monolayers on metal surfaces.
