Product Name:Potassium tartrate
English Name:Potassium tartrate
CAS No.:921-53-9
Aliases:Dipotassium tartrate, Dipotassium L-tartrate, Tartaric acid dipotassium salt
Molecular Formula:C4H4K2O6
Physical Properties:Relative molecular mass 226.27. White crystalline powder or crystals, odorless, with a cool and slightly salty taste. Freely soluble in water, slightly soluble in ethanol, insoluble in ether. The aqueous solution is neutral to slightly alkaline. Optically active, with specific rotation [α]D20 approx. +27° (in water). Relative density approx. 1.98; decomposes above 200°C.
Uses:Used as an acidity regulator, buffering agent and stabilizer in the food industry, and as a raw material for diuretics and potassium supplements in the pharmaceutical industry. It serves as a precipitating and complexing reagent for metal ions in analytical chemistry, and finds applications in electroplating, mirror manufacturing and ceramic industries. It is also used as a nutrient salt in fermentation.
Technical Specifications:
Assay (C4H4K2O6, on dry basis) ≥98.0%
Appearance: white crystalline powder or crystals free from visible impurities
pH (5% aqueous solution): 7.0–9.0
Loss on drying ≤0.5%
Solubility: freely soluble in water, giving a clear and colorless solution
