139-13-9
Product name: Nitrilotriacetic acid
English alias: NTA; Triglycine; Nitrilotriacetate
CAS: 139-13-9
Molecular formula: C6H9NO6
Appearance: White crystalline powder
Package: 25kg/drum
Nitrilotriacetic acid (NTA) is a tricarboxylic acid containing a nitrogen atom with three acetic acid groups attached. It is widely used as a chelating agent, capable of binding to metal ions such as calcium, magnesium, and iron. This ability makes NTA effective in applications requiring metal sequestration, such as industrial water treatment, cleaning formulations, textile processing, and detergents.
NTA is also used as an intermediate in chemical synthesis and in electroplating processes where precise metal ion control is necessary. It is soluble in water and forms stable water-soluble chelates. NTA can be found as a white crystalline powder, and is often supplied as its acid form or in salt forms such as NTA trisodium salt.
Number | Item | Specification | Result |
1 | Appearance | White crystalline powder | White powder |
2 | Purity (%) | ≥99.0 | 99.36 |
3 | pH (1% solution) | 2.0 – 3.0 | 2.65 |
4 | Loss on drying (%) | ≤0.5 | 0.23 |
5 | Heavy metals (Pb) | ≤10 ppm | <10 ppm |
Conclusion | PASS |
1 Nitrilotriacetic acid used as a chelating agent in water treatment to bind metal ions and prevent scaling
2 Commonly used in detergents and cleaners to soften water and improve performance
3 Nitrilotriacetic acid acts as a metal ion control agent in textile dyeing and bleaching processes
4 Nitrilotriacetic acid used in electroplating and metal finishing to control metal ion activity
5 Nitrilotriacetic acid serves as an intermediate in the synthesis of chelates, fertilizers, and other compounds
6 Applied in cosmetics and personal care for stabilization of formulations (in trace amounts)
Nitrilotriacetic acid should be handled with care. While it is low in acute toxicity, prolonged or excessive exposure may pose health risks. NTA has been classified by IARC as a Group 2B carcinogen (possibly carcinogenic to humans) based on animal studies. Therefore, appropriate protective measures should be taken during handling. It is not recommended for use in food or pharmaceutical products.
Store in a dry, cool, and ventilated area
Keep container tightly closed when not in use
Avoid exposure to moisture, heat, and direct sunlight
Recommended relative humidity: <50%
Nitrilotriacetic acid is available in sealed industrial-grade packaging to preserve product integrity. Packaging formats include:
25 kg fiber drums with inner plastic lining
500 kg and 1000 kg bags (for bulk orders)
