Trimellitic anhydride（Cat No.:R023379） is a highly reactive organic compound used predominantly in the production of polymers and resins. It appears as a white crystalline solid and is recognized for its three carboxylic acid groups, which make it an excellent anhydride for creating cross-linked structures. Common applications include the synthesis of polyimide and polyester resins, where they impart heat resistance and mechanical strength. Additionally, trimellitic anhydride is used in the manufacture of coatings, adhesives, and insulation materials. It also serves as a key intermediate in the production of certain dyes and pigments.
