Trisodium Nitrilotriacetate (NTA-3Na) is a sophisticated chemical compound characterized by its robust chelating properties, making it a staple in many industrial processes. Understanding its physical and chemical attributes is key to appreciating its benefits. NINGBO INNO PHARMCHEM CO.,LTD., as a trusted supplier from China, ensures that clients receive NTA-3Na that meets high-quality standards.

Physically, NTA-3Na typically presents as a white crystal powder. Its solubility in water is a critical advantage, allowing for easy integration into aqueous formulations and processes. While it exhibits excellent stability, its molecular structure allows it to effectively bind with a wide range of metal ions, forming stable chelate complexes. This ability is the core of its function across various applications.


Chemically, NTA-3Na has a molecular formula of C6H6NNa3O6 and a molecular weight of approximately 257.08 g/mol. Its pH value, typically in the range of 10.5-11.5 for a 5% solution, indicates its alkaline nature. This characteristic can be beneficial in certain formulations where pH adjustment is also required. The compound’s purity, often exceeding 99%, ensures reliable performance and predictable results in sensitive applications.


The primary benefit of NTA-3Na lies in its capacity to sequester metal ions. This capability is harnessed in detergent formulations to prevent the interference of hard water ions, thereby boosting cleaning efficiency. In water treatment, it is vital for removing heavy metals, contributing to environmental protection. Its role as a complexing agent in the textile industry enhances dye consistency, while in metal plating, it stabilizes solutions for better finishing quality. The consistent sourcing of NTA-3Na from reliable manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. is essential for maintaining these performance standards.


The advantages of using NTA-3Na include improved product stability, prevention of scale formation in industrial systems, and enhanced bioavailability of micronutrients in agriculture. Its broad applicability and effectiveness make it a go-to chemical for many manufacturers seeking to optimize their products and processes.
