Edetic Acid is the acid form of edetate, a chelating agent with anti-hypercalcemic and anticoagulant properties. Edetic acid binds calcium and heavy metal ions, forming soluble stable complexes which are readily excreted by the kidneys. This results in a decrease in serum calcium levels. This agent is also used as an anticoagulant for blood specimens and is applied as a treatment of lead poisoning. Edetic acid is a Lead Chelator and Anti-coagulant. The mechanism of action of edetic acid is as a Lead Chelating Activity and Calcium Chelating Activity. The physiologic effect of edetic acid is by means of Decreased Coagulation Factor Activity.

EDTA is an important complexing agent with a wide range of applications.It can be used as a bleach-fix solution for the processing of color photographic materials, dyeing auxiliaries, fiber treatment auxiliaries, cosmetic additives, blood anticoagulants, detergents, stabilizers, and initiators for synthetic rubber polymerization.EDTA is a representative chelating agent.It can form stable water-soluble complexes with alkali metals, rare earth elements, transition metals, and others.In addition to sodium salts, there are ammonium salts and various salts of iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum, etc., each with different applications. Furthermore, EDTA can be used to rapidly excrete harmful radioactive metals from the human body, thus acting as a detoxifying agent.It is also a water treatment agent.EDTA is also an important indicator used for the titration of metals such as nickel and copper.It must be used together with ammonia solution to function as an indicator.
