Ethylenediaminetetraacetic acid calcium disodium salt
Ethylenediaminetetraacetic acid calcium disodium salt (CAS: 62-33-9), with the molecular formula C10H12CaN2Na2O8 and a molecular weight of 374.27 g/mol, is a chelating agent. It is primarily utilized to mitigate enzyme inhibition caused by trace heavy metals and to inhibit enzymes that depend on divalent cations as cofactors. This specific form, pre-chelated with Ca2+, selectively targets divalent cations with a higher affinity for EDTA.

Metal Ion Chelation
Acts as a chelating agent to bind and sequester unwanted metal ions, thereby preventing their interference in sensitive biochemical reactions or processes.
Enzyme Inhibition
Used to inhibit enzymes that require divalent cations (like Mg2+ or Mn2+) as essential cofactors by chelating these ions. Its calcium-bound form also specifically displaces other more strongly bound divalent cations.
Trace Metal Scavenging
Effectively eliminates enzyme inhibition caused by the presence of trace amounts of heavy metal contaminants in experimental or industrial systems.
