Toluene is a clear, colorless liquid with a distinctive, sweet smell. It is a hydrocarbon solvent derived from petroleum and is widely used in various industrial applications. Toluene is commonly employed as a solvent in paints, coatings, adhesives, and varnishes due to its ability to dissolve a wide range of substances and its relatively low evaporation rate. It is also used in the production of chemicals such as benzene and xylene, as well as in the manufacture of explosives and pharmaceuticals. Toluene is flammable and should be handled with care, as it can be harmful if inhaled or ingested.
