Disodium tartrate dihydrate (CAS 6106-24-7) is the sodium salt of tartaric acid, appearing as a highly water-soluble, odorless crystalline powder. Its primary selling point is its versatility as a precise laboratory reagent, most notably serving as a critical water standard for calibrating Karl Fischer moisture analyzers and as a stable buffer in biochemical research.
In the pharmaceutical and food industries, it acts as an effective pH regulator (maintaining a mild pH of 7.0-9.0), antioxidant, and flavor enhancer to balance acidity. Additionally, its strong ability to chelate metal ions makes it invaluable as a stabilizer in drug formulations, a masking agent in chemical analysis, and a functional additive in industrial electroplating processes.

Disodium tartrate dihydrate (CAS 6106-24-7) is the sodium salt of tartaric acid. It typically appears as a white or colorless crystalline powder, is odorless with a slightly salty taste, and is highly soluble in water while being insoluble in ethanol.
Here are its core selling points and key applications across various industries:
Laboratory & Analytical Chemistry
Water Standard for Karl Fischer Titration: One of its most critical uses is as a precise water standard to calibrate Karl Fischer reagents for accurate moisture content analysis.
Buffer & Biochemical Reagent: It is widely used to prepare stable buffer solutions for molecular biology and cell culture. It also acts as an acid phosphatase inhibitor in biochemical research.
Chelating & Masking Agent: Its molecular structure allows it to effectively bind with metal ions (like vanadium), making it an excellent masking and chelating agent in various chemical analyses.
Pharmaceutical & Medical Applications
Buffer & Stabilizer: In pharmaceutical formulations (especially injectables like antibiotics and vitamins), it helps maintain a stable physiological pH (its aqueous solution has a pH of 7.0-9.0), preventing active ingredients from degrading.
Heavy Metal Antidote: It acts as a chelating agent that can bind to toxic heavy metals (such as lead, mercury, or copper), helping to form stable complexes that can be safely excreted from the body.
Excipient & Therapeutic Aid: It serves as a safe excipient to improve drug solubility and bioavailability in tablets. It is also used as a mild osmotic laxative and to treat excess stomach acid.
Food & Beverage Industry
Acidity Regulator & Flavor Enhancer: It provides a mild, pleasant acidity and is used to soften and balance the sharp sour taste of tartaric acid in soft drinks, wines, and candies.
Antioxidant & Stabilizer: It functions as an effective antioxidant and synergist, helping to preserve the quality, color, and freshness of jams, jellies, processed meats, and margarine.
Emulsifying Salt: It aids in the emulsification process, ensuring smooth and stable textures in various processed food products.
Industrial & Advanced Applications
Electroplating & Metal Analysis: It is utilized as a complexing agent in electroplating baths and for the micro-analysis of specific metals like vanadium.
Optical Applications: Due to its unique crystalline properties, it can be applied in advanced optical fields, such as laser frequency doubling and optical limiting.
