Application: Ethylenediaminetetraacetic acid dipotassium salt dihydrate (K2EDTA) can be used as:
•  A mobile phase modifier in the separation of UV filters using HPLC.
•  A chelating agent in the determination of traces of beryllium compound by colorimetric method.
Application: Used to eliminate inhibition of enzyme catalyzed reactions due to traces of heavy metals
General description: Ethylenediaminetetraacetic acid dipotassium salt dihydrate (K2EDTA), is a well known chelating agent with various uses in chemical synthesis, analytical chemistry, and biochemistry. In chemical synthesis, K2EDTA is often employed to remove metal impurities from solutions or as a complexation agent to control the reactivity of metal ions. It can be used to sequester or chelate metal ions such as calcium, magnesium, iron, and copper, which helps prevent undesired side reactions.
