Durene, or 1,2,4,5-tetramethylbenzene, is an aromatic hydrocarbon used as a solvent. It is also an intermediate in the manufacture of pyromellitic acid, which is used for manufacturing curing agents, adhesives and coating materials. It is used in the manufacture of some raw materials for engineering plastics (polyimides) and cross-linking agent for alkyd resins. 1,2,4,5-Tetramethylbenzene has a simple proton NMR spectrum comprising two signals due to the 2 aromatic hydrogens (2H) and four methy… (More on Durene)
