Tartaric acid (CAS: 87-69-4), chemically named 2,3-Dihydroxybutanedioic acid, is a naturally occurring alpha-hydroxy organic acid widely extracted from grapes, tamarinds and other fresh fruits. As a versatile and safe acidic ingredient, it appears as white crystalline powder or colorless transparent crystals with excellent water and alcohol solubility. With stable chemical properties, low toxicity and strong chelating ability, tartaric acid has become one of the most essential additives in food processing, daily chemicals, pharmaceutical production and modern industrial manufacturing.
