Isodurene
Isodurene or 1,2,3,5-tetramethylbenzene is an organic compound with the formula C6H2(CH3)4, classified as an aromatic hydrocarbon. It is a flammable colorless liquid which is nearly insoluble in water but soluble in organic solvents. It occurs naturally in coal tar. Isodurene is one of three isomers of tetramethylbenzene, the other two being prehnitene (1,2,3,4-tetramethylbenzene) and durene (1,2,4,5-tetramethylbenzene).[1]

Production
Industrially, isodurene can be isolated from the reformed fraction of oil refineries. It may also be produced by methylation of toluene, xylenes and trimethylbenzenes.[1]
