Trimellitic Anhydride (TCI C0046, CAS 552-30-7) is a trifunctional aromatic anhydride bearing both an anhydride ring and a free carboxylic acid group. This combination makes it a key monomer for polyimides, polyesterimides, and cross-linked alkyd or polyester resins with high thermal stability. It also serves as a starting material for trimellitate esters studied as plasticisers. The compound is a respiratory sensitiser and moisture sensitive, so handle it in a fume hood with suitable protection and store it tightly closed in a cool, dry place.
