For chemists, formulators, and R&D scientists, a deep understanding of a chemical intermediate's properties is fundamental to its successful application. 3,4,5,6-Tetrahydrophthalic Anhydride (TMMA), identified by CAS number 2426-02-0, is a versatile organic compound whose chemical and physical characteristics make it valuable across numerous industrial sectors. As a leading supplier of specialty chemicals, we provide comprehensive information on TMMA to aid our clients in their research and development efforts.

TMMA, with the molecular formula C8H8O3 and a molecular weight of approximately 152.15 g/mol, typically presents as a yellow flaky solid. Its key physical properties include a melting point in the range of 66.0-69.0 °C and a boiling point of 302.3±11.0 °C at 760 mmHg. These thermal properties indicate its stability under various processing conditions. The density of TMMA is around 1.3 g/cm³, and it exhibits a low vapor pressure (0.0±0.6 mmHg at 25°C), suggesting minimal volatility, which is beneficial for handling and storage safety. Its refractive index is recorded at 1.534.

Chemically, TMMA is a cyclic anhydride known for its reactivity. The anhydride ring readily undergoes nucleophilic attack, enabling reactions such as esterification and amidation. This reactivity is precisely what makes it an excellent intermediate for resin synthesis, where it reacts with diols to form polyesters, and as a curing agent for epoxy resins, forming cross-linked polymers. The chemical structure also permits its use as an intermediate in complex organic syntheses, including those for pharmaceuticals and agrochemicals. Understanding these reactions helps in optimizing its use and exploring new applications.
