Product Application
Ethylenediaminetetraacetic acid is an aminopolycarboxylic acid and a hexadentate ligand that forms stable octahedral complexes with many metal cations. Disodium EDTA is widely used as a blood anticoagulant and is related to pseudothrombocytopenia. It works by binding calcium ions in blood to prevent clotting, making it standard in hematology testing.
