Beschreibung

Allgemeine Beschreibung

Sodium hydrogentartrate is an inorganic salt commonly used in qualitative chemical analysis to detect potassium.

Anwendung

Sodium hydrogentartrate may also be used in the preparation of sodium citrate-sodium tartrate reagent, which can complex with interfering metals during the colorimetric estimation of ammonium ions in soil samples. The modification of supported nickel catalysts with sodium hydrogentartrate leads to enhanced enantiomeric excess (ee) during the hydrogenation of methyl acetoacetate.
