Description

Potassium sodium tartrate tetrahydrate has been used in organic synthesis to break up emulsions in aqueous workups. The compound is an ingredient of Fehling’s solution and of the reagent Biuret (sc-239384). Fehling’s solution tests for aldose and ketose functional groups. Biuret reagent measures protein concentrations. Potassium sodium tartrate tetrahydrate is a component in the technique to produce micrometer sized aerosol particles. The compound has been used as a precipitant in the crystallization and preliminary X-ray analysis of strictosidine synthase.
