Ethylenediamine-N,N,N',N'-tetraacetic acid dipotassium salt

Description:
Ethylenediamine-N,N,N',N'-tetraacetic acid dipotassium salt, commonly referred to as potassium EDTA, is a chelating agent widely used in various applications, including analytical chemistry, medicine, and agriculture. It is a white, crystalline solid that is highly soluble in water, making it effective in binding metal ions. The compound features four carboxylic acid groups and two amine groups, which enable it to form stable complexes with divalent and trivalent metal ions, such as calcium, magnesium, and lead. This property is particularly valuable in preventing metal ion interference in biochemical assays and in treating heavy metal poisoning. Additionally, potassium EDTA is utilized in food preservation and as a stabilizer in cosmetics and personal care products. Its dipotassium salt form enhances its solubility and bioavailability. While generally regarded as safe, it is important to handle it with care, as excessive exposure can lead to adverse effects. Overall, potassium EDTA is a versatile compound with significant importance in both industrial and medical fields.
