In the realm of medical diagnostics and chemical applications, the choice of anticoagulant and chelating agent is paramount. Ethylenediaminetetraacetic acid (EDTA) stands out as a versatile compound, with its dipotassium (K2) and tripotassium (K3) salt forms offering distinct advantages. Understanding these differences is key for professionals seeking to buy EDTA dipotassium salt or EDTA tripotassium salt for their specific requirements. This article delves into the properties and applications of both, guiding you to the optimal choice and highlighting reliable suppliers.

EDTA, as a potent chelating agent, works by binding to metal ions, most notably calcium. This action is fundamental to its role as an anticoagulant, preventing the cascade of reactions that lead to blood clotting. In hematology, this function is critical for preserving the fluidity and cellular integrity of blood samples, ensuring accurate diagnostic testing.

Understanding EDTA Dipotassium (K2) and EDTA Tripotassium (K3)

EDTA Dipotassium Salt (CAS 25102-12-9), also known as K2 EDTA, is characterized by its two potassium ions. It is a white, odorless, crystalline powder readily soluble in water. Its primary application is as a blood anticoagulant, especially in vacuum blood collection tubes for hematological analysis. Its ability to chelate calcium ions irreversibly maintains blood sample fluidity, preserving cell morphology and count. Beyond medical uses, K2 EDTA finds application in wastewater treatment for metal ion removal and as a preservative in the food industry. As a leading EDTA K2 manufacturer, we ensure high purity for these diverse applications.

EDTA Tripotassium Salt (CAS 65501-24-8), or K3 EDTA, features three potassium ions. Like its counterpart, it is a water-soluble white crystalline powder. While also an anticoagulant, K3 EDTA is particularly noted for its enhanced solubility and its use in the pharmaceutical industry to improve drug bioavailability by chelating metal ions. Some sources suggest K3 EDTA offers slightly superior anticoagulant properties and better inhibition of glycolysis due to potential additive components, though this can also lead to sample dilution and potential interference in certain assays.

Comparing K2 EDTA and K3 EDTA: Applications and Efficacy

When selecting an anticoagulant for blood collection, K2 EDTA is generally preferred for routine hematological tests due to its balanced properties and minimal interference with common assays. It effectively preserves cell counts and morphology, making it a staple in clinical laboratories. The availability of EDTA dipotassium dihydrate manufacturer products ensures a consistent supply for these vital diagnostic needs.

K3 EDTA, while also an anticoagulant, is often favored for specialized applications where improved solubility or specific pharmaceutical formulations are required. However, its higher price point and the potential for sample dilution or assay interference mean that K2 EDTA remains the industry standard for most blood collection purposes. Buyers seeking a reliable CAS 25102-12-9 supplier can find high-quality K2 EDTA from reputable manufacturers.
