Toluene (CAS 108-88-3) is colourless, highly flammable, water insoluble liquid with an odour like benzene. It is a monocyclic aromatic hydrocarbon produced during the process of refining crude oil for gasoline and other fuels.
Toluene is widely used as an octane booster in gasoline and is used in making paints, inks, lacquers, paint thinners, adhesives, fingernail polish, leather tanning processes, cleaning agents, rubber, detergents, dyes, glues and pharmaceuticals. Toluene is often used as a substitute for benzene in many applications. Toluene is highly volatile and can be present in the air of a workroom as vapour.
