Product Description:

Sodium bitartrate, also known as sodium hydrogen tartrate, is the sodium salt of tartaric acid. It is a white crystalline powder with the chemical formula NaHC₄H₄O₆. It is soluble in water and exhibits acidic properties due to the presence of a free carboxylic acid group. Its primary application is in the pharmaceutical industry as an excipient. It serves as an acidulant, a buffering agent, and a source of tartaric acid in effervescent formulations. It is also used as a mild laxative in some medicinal preparations. Beyond pharmaceuticals, it finds use in the food industry as an acidulant and leavening agent (e.g., in baking powder). In chemical synthesis and analytical chemistry, it can function as a chiral resolving agent for racemic mixtures of amines due to its inherent chirality derived from tartaric acid. The compound is generally recognized as safe (GRAS) for use in food and pharmaceuticals. It is a common component in tartar emetic (antimony potassium tartrate) production and is involved in various chemical processes requiring a mild organic acid salt.
