Tartaric acid was first extracted from tartar, a by-product of winemaking. Due to the presence of two asymmetric carbon atoms in the molecular structure, there are L-tartaric acid (CAS 147-71-7) and D-tartaric acid (CAS 87-69-4), MESO-tartaric acid (CAS 147-73-9) and DL-tartaric acid (CAS 133-37-9).
Tartaric acid is widely used in food, pharmaceutical, chemical, light industry, and other industries. In the food industry, tartaric acid is an excellent acidifier with 1.2-1.3 times the acidity of citric acid and unique flavor. According to the sanitary standards for food additives in China, it is mainly used in combination with citric acid and malic acid and can be used in beverages, canned food, jams, and candies. In the pharmaceutical industry, tartaric acid is used as a pharmaceutical intermediate and a highly effective splitting agent. In the chemical industry, it is used to produce tartaric acid salts and tartaric acid esters, which can be used as cleaning agents and polishing agents for metal surfaces. In the textile industry, tartaric acid is used in combination with tannins as a dyeing agent for acid dyes. In addition, tartaric acid has important applications in the leather, cement, and photographic development industries.
