Toluene /ˈtɒln/, umwhile kent as toluol /ˈtɒlɒl/, is a clear, watter-insoluble liquid wi the typical smell o paint thinners. It is a mono-substitutit benzene derivative, i.e., ane in which a single hydrogen atom frae a group o sax atoms frae the benzene molecule haes been replaced bi a univalent group, in this case CH3. As such, its IUPAC seestematic name is methylbenzene.

It is an aromatic hydrocarbon that is widely uised as an industrial feedstock an as a solvent. Lik ither solvents, toluene is sometimes an aa uised as an inhalant drug for its intoxicatin properties; however, inhalin toluene haes potential tae cause severe neurological harm.[2][3] Toluene is an important organic solvent, but is an aa capable o dissolving a nummer o notable inorganic chemicals such as sulfur,[4] iodine, bromine, phosphorus, an ither non-polar covalent substances.
