Application

Ethylenediaminetetraacetic acid calcium disodium salt hydrate is calcium and sodium salt of EDTA and it can be used:
  • To retain the quality of litchi fruit by the postharvest treatment process.
  • In the preparation of an aqueous solution for hydroxyapatite coating, which is used to coat the magnesium material/particle for biomedical applications.
  • To prepare a mobile phase for the separation of diol products from the aqueous solution of the reaction mixture by chromatography techniques.
