EDTA-2NA
EDTA-2Na (Ethylenediaminetetraacetic acid disodium salt) is a chelating agent known for its ability to bind metal ions. It forms stable complexes with a variety of metal ions, including calcium, magnesium, iron, and copper, thereby preventing their interference in chemical reactions or undesirable effects in various processes. it is water-soluble and exhibits pH-dependent chelation properties. It acts as a powerful sequestering agent, removing metal ions from solutions and preventing them from catalyzing undesirable reactions. Additionally, it finds applications in various industries, including pharmaceuticals, food, and cosmetics, owing to its ability to enhance stability and shelf-life by inhibiting metal-induced degradation reactions.
