2-Isopropylbenzenethiol is primarily used in the synthesis of organic compounds, particularly in the production of pharmaceuticals and agrochemicals. Its thiol group makes it a valuable intermediate in creating sulfur-containing molecules, which are often key components in drugs and pesticides. Additionally, it serves as a building block in the development of specialty chemicals, including fragrances and flavors, due to its distinct aromatic properties. In research, it is employed as a reagent in various chemical reactions, especially those involving sulfur chemistry, to study reaction mechanisms or develop new synthetic pathways. Its application extends to material science, where it is used in modifying surfaces or creating polymers with specific properties.
