For chemists, formulators, and procurement specialists in the B2B sector, a deep understanding of chemical properties is fundamental to successful product development and sourcing. 1,2,4-Benzenetricarboxylic Acid (CAS 528-44-9), commonly known as Trimellitic Acid, is a fine chemical intermediate with distinct characteristics that make it highly valuable across multiple industries. As a dedicated manufacturer and supplier, we aim to provide clear insights into this crucial compound.

Chemical Identity and Structure

1,2,4-Benzenetricarboxylic Acid possesses the molecular formula C9H6O6 and a molecular weight of 210.15 g/mol. Its structure features a benzene ring with three carboxylic acid groups attached at the 1, 2, and 4 positions. This trifunctional nature is key to its reactivity and its utility as a cross-linking agent or a building block in polymer synthesis. Synonyms like Trimellitic acid, 1,2,4-Tricarboxybenzene, and 4-Carboxyphthalic acid are commonly used, which is important to note when searching for suppliers or product information online.

Key Physical and Chemical Properties

Typically supplied as a white crystalline powder, 1,2,4-Benzenetricarboxylic Acid exhibits moderate solubility in water, with a reported solubility of 2.1 g/100 mL at 25°C. It is partially soluble in solvents like DMF and alcohol, but insoluble in nonpolar solvents such as benzene and carbon disulfide. Its melting point is around 229-231°C with decomposition. These properties dictate its handling, storage, and application parameters. Understanding these details is crucial for R&D scientists when evaluating materials for specific synthesis routes.

Why Trimellitic Acid is a Preferred Intermediate
