EDTA disodium salt dihydrate is widely used in various industries due to its chelating properties. In the food industry, it acts as a preservative by binding metal ions that can catalyze spoilage, thereby extending the shelf life of products like canned goods and beverages. In medicine, it is utilized as an anticoagulant in blood collection tubes, preventing blood clotting by sequestering calcium ions. Additionally, it is employed in chelation therapy to treat heavy metal poisoning, effectively removing toxic metals such as lead and mercury from the body. In the cosmetic industry, it enhances the stability and shelf life of products by preventing degradation caused by metal ion contamination. It is also used in water treatment processes to control water hardness by binding calcium and magnesium ions, preventing scale formation in boilers and pipes. In analytical chemistry, it serves as a complexometric titrant for determining metal ion concentrations in solutions. Its versatile applications make it an essential compound in numerous fields.
