Ethylenediaminetetraacetic acid (EDTA) sodium hydrate is a metal chelator that binds with divalent and trivalent metal cations, including calcium. It exhibits antibacterial, anti-inflammatory, antioxidant, anti-hypercalcemic, and anticoagulant properties. EDTA sodium hydrate reduces protein oxidation damage catalyzed by metal ions and maintains a reducing environment during protein purification, making it a common choice for protein purification and storage. Additionally, it can alleviate liver fibrosis and is used in research related to coronary artery disease and neurological disorders.
