For industrial buyers, selecting the right chemical supplier is as critical as selecting the right chemical itself. High-purity EDTA 4Na (Tetrasodium EDTA) is a versatile chelating agent vital for numerous applications, from improving detergent efficacy to stabilizing pharmaceuticals. NINGBO INNO PHARMCHEM CO.,LTD. offers guidance on what industrial buyers should consider when sourcing this essential compound.

1. Purity and Grade: The first and most crucial factor is purity. For most industrial applications, a high purity level, typically 99% or higher, is required. Different grades may exist, but for applications in detergents, cosmetics, pharmaceuticals, and advanced water treatment, high purity ensures optimal performance and minimizes the risk of adverse reactions. Always verify the assay percentage, often indicated by 'Assay by wt %' in product specifications.

2. Chemical Specifications and CAS Number: Understanding the chemical identity is vital. The CAS Number for Tetrasodium EDTA is widely recognized as 13235-36-4. Confirming the molecular formula (C10H12N2Na4O8) and ensuring it matches the product description is essential. Key specifications to look for include low levels of impurities like chloride (Cl), sulfate (SO4), heavy metals (Pb), and iron (Fe), along with a specific pH range (typically 10.5-11.5 for a 1% solution) and chelating value.

3. Applications and Suitability: While EDTA 4Na is broadly applicable, buyers should ensure the specific grade and specifications meet their intended use. For example, using a technical grade for industrial cleaning might be acceptable, but pharmaceutical applications demand pharmaceutical-grade purity. NINGBO INNO PHARMCHEM CO.,LTD. can provide product information tailored to specific industry needs, whether for detergent formulations, water treatment, or cosmetic ingredient requirements.

4. Packaging and Delivery: Industrial quantities often come in large packaging, such as 25kg kraft paper bags, woven bags, or jumbo bags. Buyers should consider their storage and handling capabilities. Reliable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. ensure secure packaging and efficient logistics, often offering options like palletized or non-palletized full container loads to meet delivery timelines and supply chain demands.

5. Supplier Reliability and Support: Beyond the product itself, the reliability of the supplier is paramount. Look for suppliers with a proven track record, certifications (like ISO), and strong customer support.
