Trimellitic anhydride

Trimellitic anhydride is a 2-benzofuran compound having oxo groups at the 1- and 3-positions and a carboxy substituent at the 5-position; the cyclic anhydride formed from the carboxy groups at the 1- and 2-positions of trimellitic acid. It has a role as an allergen, an epitope and a hapten. It is a dioxo monocarboxylic acid, a cyclic dicarboxylic anhydride and a member of 2-benzofurans. It is functionally related to a trimellitic acid and a phthalic anhydride. — ChEBI
