Dipotassium EDTA / EDTA K2

Dipotassium EDTA, also known as EDTA K2, is a white crystalline powder with a molecular weight of 404.6 and a pH of 4.8±1 in a 5% aqueous solution. It is highly soluble in water, with a minimum solubility of 60% at 25°C, and readily absorbs moisture from the air. The product is stable under ambient conditions and contains at least 99.0% EDTA by weight, as verified by the supplier's test report. This grade is specifically formulated for use in hematological applications where precise anticoagulation is required.

It functions as an anticoagulant by chelating calcium ions in blood samples, preventing clot formation without altering white blood cell counts or red blood cell morphology. Compared to tripotassium EDTA, it has lower solubility and a slower anticoagulation rate, making it less ideal for platelet kinetic studies but preferred for routine CBC testing. The International Committee for Hematology Standardization recommends dipotassium EDTA as the standard anticoagulant for blood cell counting and differential analysis. It is unsuitable for coagulation assays, calcium measurements, or PCR testing due to interference with enzyme activity and ion-dependent reactions.

This product is supplied in 500g plastic bottles, sealed to limit moisture absorption during transit. Buyers typically include clinical laboratories, diagnostic kit manufacturers, and pharmaceutical formulators sourcing for in-vitro diagnostic reagents. The supplier does not disclose minimum order quantities or lead times; these must be confirmed directly. Trade terms such as Incoterms and payment methods are not listed and require direct negotiation with the supplier.

Hubei Desheng Material Technology Co., Ltd is located in Ezhou City, Hubei Province, China, with a registered address in the Gaoxin 3rd Road industrial zone. The company is categorized as a harbor-tier supplier, indicating basic verification of legal registration and operational existence. There is no public data on years in business, production capacity, or client list. The supplier does not respond to inquiries, as indicated by a 0.00% response rate and zero average response hours, which suggests limited buyer support infrastructure.

The listing confirms only the product's chemical identity and physical properties, with no mention of certifications, R&D capabilities, or export experience. The absence of response metrics and detailed profile information implies this is a basic trading or manufacturing entity focused on bulk chemical supply rather than value-added services. Buyers should treat this as a raw material source and verify all technical claims independently.
