Descriptions:
pubchem: Phthalic anhydride is the cyclic dicarboxylic anhydride that is the anhydride of phthalic acid. It has a role as an allergen. It is a cyclic dicarboxylic anhydride and a member of 2-benzofurans.
chebi: The cyclic dicarboxylic anhydride that is the anhydride of phthalic acid.
chembl: PHTHALIC ANHYDRIDE is a small molecule listed in the ChEMBL database but has not progressed to an approved clinical phase.
wikipedia: Phthalic anhydride is the organic compound with the formula C6H4(CO)2O. It is the anhydride of phthalic acid. Phthalic anhydride is a principal commercial form of phthalic acid. It was the first anhydride of a dicarboxylic acid to be used commercially. This white solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics. In 2000, the worldwide production volume was estimated to be about 3 million tonnes per year.
