Toluene is a colorless, water-insoluble liquid with the chemical formula C7H8. It is an aromatic hydrocarbon and is commonly used as a solvent, fuel additive, and precursor to various chemicals such as benzene, toluene diisocyanate, and trinitrotoluene (TNT). Toluene has a distinctive sweet, pungent odor, a relatively low boiling point, and is highly flammable. It is classified as a hazardous substance due to its potential health and environmental hazards, such as its toxicity and ability to form explosive mixtures with air. Long-term exposure to toluene can cause neurological damage, while acute exposure can cause headaches, dizziness, and respiratory problems.
