Structural Formula:

1· Performance and Applications

EDTMPA is white crystalline powder at room temperature, with a melting point of 215-217℃, slightly soluble in water (solubility less than 5% at room temperature), and easily soluble in ammonia water.

EDTMPA is a high-purity reagent with non-toxic property and strong ability to chelate metal ions. In the electronic industry, it can be used as a cleaning agent for semiconductor chips in the manufacture of integrated circuits; in the pharmaceutical industry, it is used as a carrying agent for radioactive elements for disease examination and treatment.

2· Technical Specifications

We can provide citric acid with 99% encapsulation purity for electronic, pharmaceutical and other industries.

3· Packaging and Storage

EDTMPA is packed in composite plastic woven bags or packaging meeting export environmental protection requirements, with a net weight of 25kg per bag. Store in a cool indoor place. The shelf life is ten months.

4· Safety Protection

EDTMPA is an acidic solid. Pay attention to labor protection during operation. Avoid contact with skin, eyes, etc. In case of contact, rinse immediately with plenty of clean water.
