Structural formula:
Performance and Applications:
At room temperature, EDTMPA is a white crystalline powder with a melting point of 215–217°C. It is slightly soluble in water, with a solubility of less than 5% at room temperature, but readily soluble in ammonia solution.
EDTMPA is a high-purity reagent that is non-toxic and possesses strong chelating ability for metal ions. In the electronics industry, it can be used as a cleaning agent for semiconductor chips in the manufacture of integrated circuits; in the pharmaceutical industry, it serves as a carrier for radioactive elements in the diagnosis and treatment of diseases.

Our company can supply citric acid with a purity of 99% (encapsulated purity), suitable for industries such as electronics and pharmaceuticals.
Packaging and Storage:
EDTMPA is packaged in composite plastic woven bags or in packaging that meets export environmental protection requirements. Each bag has a net weight of 25 kg and should be stored in a cool, indoor location for a shelf life of ten months.
Security protection:
EDTMPA is an acidic solid. When handling it, pay attention to occupational safety measures and avoid contact with skin, eyes, and other body parts. If contact occurs, rinse thoroughly with plenty of water.
