Descripción

General description

Sodium L-tartrate is an organic acid mainly found in grapes.

Application

Sodium L-tartrate dibasic dihydrate may be used in the preparation of solid-state M–L compounds (M = bivalent metal ions ie., Mn, Fe, Co, Ni, Cu, Zn; L = tartrate). It may also be used in the preparation of copper (II) and cobalt (II) tartrate complexes by reacting with the corresponding metal salts. These complexes can undergo thermal decomposition to form Cu and Co metal oxide nanoparticles.
