EDTA disodium salt dihydrate, EDTA-Na2 · 2 H2O, Titration complex III
Empirical formula C10H14N2Na2O8 · 2 H2O
Molar mass (M) 372,24 g/mol
Melting point (mp) 110 °C
WGK 2
CAS No. 6381-92-6
EG-Nr. 205-358-3

For molecular biology and biochemistry.
Application: Stock solution: 0.5 M in water, pH 8.5. Recommended final concentration for enzyme inhibition 1-10 mM. The disodium salt of EDTA only dissolves when the pH-value is around 8.0.

EDTA forms chelate complexes with Mg2+-ions and other bivalent metal cations. It can therefore be applied as a general inhibitor for all enzymes which require such metal cations to function (e.g. DNases and metal proteases).
