Chemische Eigenschaften
white powder
Verwenden
Used to eliminate enzyme inhibition by traces of heavy metals, and to inhibit enzymes that require divalent cations as cofactors. As this form is already chelated with Ca²⁺, it is selective for divalent cations with greater affinity for EDTA, which it will exchange for Ca²⁺.
Verwenden
Chelating agent (metal).
Verwenden
EDTA calcium disodium is a sequestrant and chelating agent whose complete name is disodium calcium ethylenediamine tetraacetate. It is a nonhygroscopic powder that is colorless, odorless, and tasteless at recommended use levels. A 1% solution has a ph of 6.5–7.5. It is used to control the reaction of trace metals with some organic and inorganic components in food; to prevent deterioration of color, texture, and development of precipitates; and to prevent oxidation. Its function is comparable to that of disodium dihydrogen edta. It is also termed calcium disodium edta.
Definition
ChEBI: EDTA monocalcium diisodium salt is an organic calcium salt of EDTA diisodium. It is a chelating agent that is used for the treatment of lead poisoning. It has a role as a geroprotector, a chelator and an antidote. It contains an EDTA disodium salt (anhydrous).

Pharmazeutische Anwendungen
Calcium disodium edetate, also referred to as calcium sodium EDTA, stands for the chemical compound 2,2 ,2 ,2 -(ethane-1,2-diyldinitrilo)tetraacetic acid, which is a synthetic amino acid. Edetate refers to the calcium disodium salt of the chelating agent with the formula (HO₂CCH₂)₂NCH₂CH₂N(CH₂CO₂H)₂. In the United States, it is found under the name calcium disodium versenate. Edetate is mainly used to complex di and trivalent metal ions. Edetate can bind to metals via the four carboxylate and two amine groups, and it forms specially strong complexes with Co(III), Cu(II), Mn(II) and Fe(III). Dimercaprol (BAL, British anti-Lewisite), calcium disodium edetate and penicillamine are the three most common chelating agents used in the treatment of heavy-metal poisoning.
