Tartaric Acid
Tartaric acid, 2,3-dihydroxysuccinic acid, is a carboxylic acid that is found in many plants, such as grapes and tamarind, and is one of the main organic acids in wine. As an antioxidant added to food, it can make food taste sour. The biggest use of tartaric acid is in beverage additives. It is also a raw material for the pharmaceutical industry. In the lens manufacturing industry, tartaric acid is an important auxiliary and reducing agent, which can control the formation speed of silver mirrors and obtain a very uniform coating.| DL-Tartaric Acid | ||
