EDTA Dipotassium Salt, a derivative of ethylenediaminetetraacetic acid, is a chemical compound renowned for its exceptional chelating abilities. Its significance spans across critical sectors, from medical diagnostics to industrial applications. As a prominent EDTA dipotassium manufacturer, we are dedicated to providing high-quality chemical reagents that drive innovation and ensure reliability in various processes.
The chemical structure of EDTA Dipotassium (CAS 25102-12-9) features an EDTA molecule complexed with two potassium ions. This structure grants it a strong affinity for multivalent metal cations, particularly divalent and trivalent ions like calcium (Ca2+), magnesium (Mg2+), iron (Fe3+), and copper (Cu2+). By forming stable, water-soluble chelate complexes, EDTA Dipotassium effectively sequesters these metal ions, preventing them from participating in unwanted chemical reactions.
Water Solubility: EDTA Dipotassium is highly soluble in water, a property that facilitates its incorporation into aqueous solutions and formulations. This characteristic is vital for its application in blood collection tubes, where it needs to be evenly distributed within the tube or on its inner surface.
pH Stability: It exhibits good stability across a relevant pH range, typically around pH 4.8 ± 1 for a 5% aqueous solution. This stability ensures its efficacy in various applications without significant degradation.
Chelating Strength: Its defining property is its potent chelating ability, particularly for calcium ions. This makes it an effective anticoagulant in hematology, preventing blood from clotting by removing essential calcium ions from the coagulation pathway.
1. Medical and Diagnostic Applications: Primarily used in blood collection tubes as an anticoagulant, EDTA Dipotassium preserves blood cell morphology and counts, essential for accurate hematological tests. It is also utilized in cell culture and DNA extraction.
2. Industrial Uses: In wastewater treatment, it chelates heavy metal ions, aiding in pollution control. It also serves as a stabilizer in detergents, textiles, and paper manufacturing.
3. Food and Cosmetics: As a food additive, it prevents oxidation and discoloration. In cosmetics, it acts as a chelating agent to improve product stability.
