Trimesic acid, also known as benzene-1,3,5-tricarboxylic acid, is an organic compound with the formula C6H3(CO2H)3. It is one of three isomers of benzenetricarboxylic acid.[3] A colorless solid, trimesic acid has some commercial value as a precursor to some plasticizers.[4]

Trimesic acid can be combined with para-hydroxypyridine to make a water-based gel, stable up to 95 °C.[5]

Trimesic acid crystallizes from water to form a hydrogen-bonded hydrated network with wide unidimensional empty channels.[6][7]
