Trimethylbenzenes

The trimethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with three methyl groups (–CH₃) as a substituent. Through their different arrangement, they form three structural isomers with the molecular formula C₉H₁₂. They also belong to the group of C₃-benzenes. The best-known isomer is mesitylene.
