Description

Potassium sodium L-tartrate tetrahydrate is used in the process of silvering mirrors. It is an active ingredient in Fehiling’s solution and Nylander’s test involved in the determination of reducing sugars. It is utilized to break up emulsion in organic synthesis as well as a common precipitant in protein crystallography. As a Biuret reagent, it is used to measure the protein concentration. Furthermore, it is used as a laxative and is also used in food industry.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
