C2H53NH3PO4

C2H53NH3PO4 is a chemical compound with the molecular formula C2H53NH3PO4. It is a derivative of phosphoric acid and ammonia, with an ethyl group substituted for one of the hydrogens in ammonia. This compound is known by several names, including ethylenediaminetetraacetic acid (EDTA) and ethylenediaminetetraacetic acid tetraethyl ester.

EDTA is a hexadentate ligand, meaning it can bind to six metal ions simultaneously. This property makes it useful in chelation therapy, a medical treatment that involves the use of EDTA to remove toxic metal ions from the body. EDTA is also used in water treatment to remove heavy metal ions and in agriculture as a soil conditioner.

The compound is typically prepared by reacting phosphoric acid with ethanolamine in the presence of a base. It is a white, crystalline solid that is soluble in water and most organic solvents. EDTA is stable under normal conditions but can decompose under strong heat or acid conditions.

EDTA has a wide range of applications beyond chelation therapy. It is used in the food industry as a preservative and emulsifier, and in the cosmetics industry as a skin conditioning agent. It is also used in the production of certain polymers and in the formulation of certain pharmaceuticals.

However, EDTA should be handled with care due to its potential toxicity. It can cause skin and eye irritation, and in high concentrations, it can be harmful if ingested or inhaled. Proper safety measures should be taken when handling this compound.
