Ethylenediaminetetraacetic acid disodium salt (EDTA-2Na) is a cornerstone chemical in many industrial and laboratory applications due to its exceptional chelating properties. Understanding its chemical makeup and how it functions is key to appreciating its widespread use. NINGBO INNO PHARMCHEM CO.,LTD. provides high-purity EDTA disodium salt, enabling a deeper understanding of its scientific underpinnings and practical benefits.

At its core, EDTA disodium salt is a derivative of ethylenediaminetetraacetic acid, a hexadentate ligand. This means it can form stable coordination complexes with a wide range of metal ions. The structure of EDTA features four carboxylate groups and two amine nitrogen atoms, which collectively surround and bind to a metal ion, effectively sequestering it. This process, known as chelation, is the primary reason for its utility. The disodium salt form, often appearing as a white crystalline powder, offers improved solubility and handling characteristics compared to the free acid form, making it a preferred choice for many applications, including EDTA disodium salt water treatment.

The chemical formula for EDTA disodium salt dihydrate is C10H14N2Na2O8·2H2O, and it typically has a molecular weight of around 372.24 g/mol. Its purity, often specified as 99% or higher, is critical for consistent performance, especially in sensitive applications like pharmaceuticals and food preservation, although this article focuses on its industrial uses such as in oil drilling. The EDTA disodium salt CAS number, commonly 6381-92-6, serves as a unique identifier for this chemical compound in global databases. When considering where to buy EDTA disodium salt online, one must prioritize suppliers who can confirm these specifications.

The chelating mechanism of EDTA disodium salt is highly effective across a broad pH range, although its efficacy is pH-dependent. This versatility allows it to be employed in diverse industrial processes where metal ion control is necessary. From preventing metal-catalyzed degradation in cosmetics to enhancing the effectiveness of cleaning agents, its chemical properties make it indispensable. For businesses seeking to optimize their processes, understanding the detailed EDTA disodium salt chemical properties is crucial for selecting the right grade and application strategy.
