For procurement professionals in the pharmaceutical, diagnostic, and chemical industries, sourcing high-quality EDTA Tripotassium Salt (CAS 65501-24-8) is a critical decision. This essential chemical plays a pivotal role as an anticoagulant additive in blood collection tubes, ensuring the integrity of samples for a wide range of diagnostic tests. As a direct manufacturer and supplier from China, we aim to guide buyers through the essential considerations when purchasing this vital component.

The primary specification to scrutinize is purity. High-purity EDTA K3, typically ≥99.0% or even ≥99.5%, is crucial for reliable performance. Impurities can interfere with the chelation process, potentially leading to inadequate anticoagulation or adverse effects on blood cell morphology. Therefore, always request a Certificate of Analysis (CoA) detailing the product's purity, appearance (white crystalline powder), odor (odorless), solubility, and the absence of harmful contaminants like heavy metals. Understanding the chemical formula (C10H17K3N2O10) and molecular weight (442.54 g/mol) is also key to ensuring compatibility with your formulations.

When evaluating suppliers, consider their production capacity, export experience, and commitment to quality control. A manufacturer with ISO certifications and a proven track record of supplying globally is a strong indicator of reliability. Furthermore, responsive customer service and technical support are invaluable, especially when addressing specific application challenges or customization needs. We, as a dedicated supplier, pride ourselves on offering not just a superior product but also comprehensive support. For buyers looking to buy EDTA K3, engaging with manufacturers who can provide consistent supply, competitive pricing for bulk orders, and timely delivery from China is paramount. Our established supply chain and experienced foreign trade team ensure that your procurement process is smooth and efficient, meeting your production schedules and quality demands.
