Chemistry & industry
Applications
UsesSodium salt of L-(+)-Tartaric Acid (T007630), a naturally occurring chemical compound found in berries, grapes and various wines. It provides antioxidant properties and contributes to the sour taste within these products.
UsesSodium 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.
UsesDisodium tartrate dihydrate is used in standardization of Karl fischer reagent to determine trace ammount of water (less than 1%).
General DescriptionSodium tartrate dihydrate is a solid standard with water content of 15.66% determined by the technique of loss on drying at 150°C. Its preparation from high-purity reagents and analysis is completed in an ISO/IEC 17025 and ISO 17034 accredited calibration laboratory.
