Pyromellitic Acid 99.0% (PMA) – Purified Intermediate from PMDA
- Pyromellitic Acid 99.0% (PMA), also known as Benzene-1,2,4,5-tetracarboxylic acid, is a high-purity intermediate obtained by controlled hydrolysis of Pyromellitic Dianhydride (PMDA).
- The hydrolysis process is repeated four to five times to ensure complete conversion and remove residual anhydrides and metallic impurities.
- The use of deionized water throughout the process significantly reduces metal ion content, ensuring consistent and repeatable product quality.
- It is widely used in specialty polymers, MOF materials, electronic chemicals, and research-grade applications where low metal content and consistent purity are critical.

Why Choose Pyromellitic Acid 99.0% Purity?
Compared with lower-grade PMA, Pyromellitic Acid 99.0% offers improved reaction consistency, lower impurity interference, and better reproducibility in downstream synthesis.
High-purity PMA is especially important for applications such as PMDA regeneration, MOF synthesis, and electronic material intermediates, where metal ions and organic residues can affect final product performance.
Key Applications of Pyromellitic Acid (PMA)
- Intermediate for PMDA regeneration and purification
- Raw material for Metal-Organic Frameworks (MOFs)
- Specialty polymers and high-performance resins
- Electronic chemicals and laboratory-grade synthesis
- Research and custom chemical formulations
