Pentamethylbenzene is an organic compound with the formula C6H(CH3)5. It is a colourless solid with a sweet odor. The compound is classified as an aromatic hydrocarbon. It is a relatively easily oxidized benzene derivative, with E1/2 of 1.95 V vs NHE.
==Synthesis and reactions== It is obtained as a minor product in the Friedel–Crafts methylation of xylene to durene (1,2,4,5-tetramethylbenzene). Like durene, pentamethylbenzene is rather electron-rich and undergoes electrophilic substitution readily. Indeed, it is used as a scavenger for carbocations.
