Product Description:

(2R,3R)-2,3-Dihydroxysuccinic acid, commonly known as L-tartaric acid, is a naturally occurring dicarboxylic acid with two chiral centers. It is the dextrorotatory enantiomer of tartaric acid and is widely distributed in plants, particularly in grapes. Structurally, it features two hydroxyl groups and two carboxyl groups, making it a versatile organic acid. Its primary application is as an acidity regulator and acidulant in the food and beverage industry, where it is used to enhance flavor, control pH, and act as a preservative. It is a key component in baking powder, confectionery, and wine production. In the pharmaceutical sector, L-tartaric acid serves as a pharmaceutical excipient, functioning as a pH adjuster, buffering agent, and chiral resolving agent for the synthesis of active pharmaceutical ingredients (APIs). It is also utilized in the production of effervescent tablets and as a stabilizer. Additionally, L-tartaric acid is employed in the chemical industry as a raw material for the synthesis of chiral compounds and metal complexes. It is generally recognized as safe (GRAS) by regulatory authorities and is highly soluble in water, with a characteristic sharp, sour taste.
