Introduction to Ethylenediaminetetraacetic Acid (EDTA) CAS 60-00-4
Ethylenediaminetetraacetic acid (EDTA) is an organic compound with the chemical formula C₁₀H₁₆N₂O₈. It appears as a white powder at room temperature and pressure. It is a chelating agent that can bind with divalent metal ions such as Mg²⁺, Ca²⁺, Mn²⁺, Fe²⁺, etc. Due to the fact that most nucleases and some proteases require Mg²⁺ for their action, they are commonly used as inhibitors of nucleases and proteases; it can also be used to remove the inhibitory effect of heavy metal ions on enzymes.

Ethylenediaminetetraacetic Acid (EDTA) CAS 60-00-4 Applications
EDTA is an important chelating agent. EDTA has a wide range of applications and can be used as a bleaching and fixing solution for color photosensitive materials, a dyeing aid, a fiber processing aid, a cosmetic additive, a blood anticoagulant, a detergent, a stabilizer, and a synthetic rubber polymerization initiator. EDTA is a representative substance of chelating agents. Can form stable water-soluble complexes with alkaline earth metals, rare earth elements, and transition metals. In addition to sodium salts, there are also ammonium salts and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum, etc. These salts have different uses. In addition, EDTA can also be used to rapidly excrete harmful radioactive metals from the human body for detoxification. It is also a water treatment agent. EDTA is still an important indicator, but when used to titrate metals such as nickel and copper, it must be used together with ammonia water to function as an indicator.
