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.

Textile printing and dyeing: In the textile printing and dyeing process, EDTA -4Na is mainly used to remove metal ions from fabrics.
Paper industry: In the papermaking process, it can be used to treat papermaking water.
Pharmacy: industry EDTA -4Na can be used to prepare drug complexes. The metal ions in some drugs may affect the stability and efficacy of the drug. By chelating with EDTA -4Na, these metal ions can be stabilized, thereby improving the quality of the drug.
