1-Heptanethiol is primarily used as a chemical intermediate in the synthesis of various organic compounds. Its applications include serving as a precursor in the production of surfactants, lubricant additives, and corrosion inhibitors. In the field of materials science, it is utilized for surface modification, particularly in the creation of self-assembled monolayers (SAMs) on metal surfaces, which can enhance properties like hydrophobicity or provide protective coatings. Additionally, 1-heptanethiol finds use in the flavor and fragrance industry, where it contributes to the development of specific aroma profiles due to its strong, sulfurous odor. It is also employed in research and development for studying thiol-based chemical reactions and their mechanisms.
