Toluene is a colorless, aromatic liquid that is commonly used as an industrial solvent. It is derived from petroleum and has a sweet smell. Toluene is often found in products like paint thinners, adhesives, and nail polish removers. Due to its ability to dissolve many substances, it plays a crucial role in various chemical processes. In addition to its use as a solvent, toluene is also a precursor in the production of other chemicals, such as benzene and xylene. While toluene has many practical applications, it can be hazardous if inhaled or ingested, leading to health concerns that require careful handling.
