<Toluene> is methylbenzene, $\mathrm{C_6H_5CH_3}$. It combines an aromatic ring with a benzylic methyl group, which creates reaction sites with different electronic environments.
It is a common organic solvent. Oxidation and substitution can affect either the side chain or the ring depending on reagents and mechanism, so identifying the reacting position is central to describing a toluene transformation.
