IDS and Other Chelator Products
EDTA -4Na is the abbreviation for Ethylene diamine tetraacetic acid tetrasodium salt. Its chemical formula is C10H12N2Na4O8, and structurally, it has two more sodium ions than EDTA -2Na. Like EDTA -2Na, it also has strong chelating ability. The two amino nitrogen atoms and four carboxyl oxygen atoms in the molecule act as coordinating atoms, which can form stable complexes with various metal ions.
