For professionals in the chemical industry, understanding the precise specifications of raw materials like Ethylenediaminetetraacetic Acid Disodium Salt (EDTA-2Na) is crucial for ensuring product quality and process efficiency. Sourcing the correct grade of EDTA-2Na means looking beyond just the product name and delving into key technical parameters that dictate its suitability for specific applications. As a leading EDTA-2Na supplier, we aim to demystify these specifications for our clients.

The most fundamental identifier is the CAS Number: 6381-92-6, which specifically denotes EDTA Disodium Salt dihydrate. When you intend to buy EDTA-2Na, always confirm this CAS number. Equally important is the assay or purity level, typically expressed as a percentage (e.g., ≥99.0% or ≥99.5% for cosmetic and food grades). Other critical specifications include Chloride (Cl) content, Sulfate (SO4) content, and limits for heavy metals like Lead (Pb) and Iron (Fe), often measured in parts per million (ppm) or mg/Kg. The pH value of a 5% aqueous solution (typically 4.0-5.0) and the chelate value (often specified as mg CaCO3/g) are also vital indicators of quality and performance. For manufacturers in China, adhering to these standards is paramount. We pride ourselves on being a reliable EDTA-2Na manufacturer that consistently delivers products meeting these rigorous specifications, ensuring optimal performance for your applications.

By prioritizing these specifications when selecting an EDTA-2Na supplier, businesses can mitigate risks associated with product variability and ensure their final products meet consumer expectations. A transparent and quality-focused EDTA-2Na supplier will readily provide comprehensive technical data to support your purchasing decisions.
