DL-tartaric acid 99% [133-37-9]
DL-tartaric acid and its salts are used as food additives to regulate acidity. They are labeled in accordance with European Union standards: tartaric acid E334, sodium tartrate E335, potassium tartrate E336, sodium potassium tartrate E337. Tartaric acid and its salts are also used in the production of processed cheeses. Potassium antimonyl tartrate (COOK- (CHOH) 2COOSbO), also known as an emetic, was used as an emetic. Tartaric acid or sodium hydrogen tartrate is used in chemical analysis to detect potassium ions.
