Properties: EDTA disodium salt dihydrate is a white crystalline powder with good solubility in water. It exhibits excellent chelating properties and can form stable complexes with metal ions.
Uses: It is mainly used as a chelating agent and finds wide applications in chemical analysis, biochemistry, pharmaceuticals, etc. It is used in chelating filter paper, metal ion analysis, cell culture, pharmaceutical formulations, food additives, and more.
Synthesis: EDTA disodium salt dihydrate is typically prepared by reacting EDTA acid (ethylenediaminetetraacetic acid) with sodium hydroxide to form EDTA disodium salt, followed by crystallization and dehydration to obtain the dihydrate form.
Safety: EDTA disodium salt dihydrate is generally considered safe for most applications when used properly. However, it should be handled carefully and not mixed with strong oxidizers or acids to avoid adverse reactions. In cases of prolonged exposure or ingestion in large quantities, it may cause irritation to the eyes, skin, or gastrointestinal tract. Proper personal protective equipment should be worn when handling this compound.
