Trimellitic anhydride is an organic compound with the formula HO2CC6H3(C2O3). It is the cyclic anhydride of trimellitic acid. Several thousand tons of this colorless solid are produced annually as a precursor to plasticizers for polyvinyl chloride. It is produced by air-oxidation of 1,2,4-trimethylbenzene.[1]
