Toluene is a colorless, aromatic liquid commonly used as an industrial solvent. It is derived from petroleum and is known for its ability to dissolve various substances, making it useful in paint thinners, adhesives, and coatings. Toluene has a sweet smell and is often found in products like nail polish remover and some types of gasoline. In addition to its use as a solvent, toluene is also a precursor in the production of chemicals such as benzene and xylene. However, exposure to toluene can pose health risks, including effects on the nervous system, so proper safety measures are essential when handling it.
