Product Overview

Calcium disodium ethylenediaminetetraacetate (EDTA-CaNa2) is a stable chelating agent and an important form of EDTA metal complex. It exhibits good water solubility and excellent metal ion control capabilities. Its molecular structure already contains pre-chelated calcium ions, making it less likely to undergo displacement reactions with calcium ions in the system during use, thus maintaining system stability.

This product is used in various industrial and formulation systems to control trace metal ion interference, preventing discoloration, precipitation, or performance degradation caused by metal catalysis. It is particularly suitable for applications requiring high system stability and safety.
