Toluene is a colorless, aromatic hydrocarbon that is commonly used in various industries. Here are some of its common uses:

• Solvent: Used to dissolve paints, coatings, varnishes, and adhesives in industrial and household applications.
• Chemical Intermediate: Serves as a precursor in the production of chemicals like benzene, xylene, and other aromatic compounds.
• Fuel Additive: Sometimes added to fuels to enhance octane ratings and improve engine performance.
• Paint Thinner: Commonly used as a thinner for oil-based paints and coatings.
• Laboratory Reagent: Used in laboratories for various chemical reactions and analyses.
• Aromatic Hydrocarbon Production: Involved in the synthesis of chemicals used in the manufacture of plastics, synthetic fibers, and resins.

Note: Toluene is flammable and can be harmful if inhaled or ingested, so it should be used with proper safety precautions.
