VWR® di-Sodium L(+)-tartrate dihydrate (≥99%) is a high-purity crystalline salt supplied under the GPR RECTAPUR® grade, ensuring excellent quality for general laboratory and industrial use. It is the sodium salt of tartaric acid and is widely used in analytical chemistry, buffer preparation, food analysis, and electroplating applications.
Due to its strong chelating properties and reducing action, sodium tartrate is also employed in Fehling’s solution as a reagent for the detection of reducing sugars. Its controlled impurity levels (arsenic ≤2 ppm, heavy metals ≤10–100 ppm) make it a reliable reagent for research and routine testing.
