NSC 6495 - Introduction
DL-2-Hydroxybutyric Acid is an organic compound with the chemical formula C4H8O3. It is a colorless crystalline solid, soluble in water and many organic solvents.
One of the main uses of DL-2-Hydroxybutyric Acid is as an additive in the food and pharmaceutical industries. It can be used as a food acid and antioxidant, and is often added to beverages, candy, bread and other foods to increase the sour taste and extend the shelf life. In addition, DL-2-Hydroxybutyric Acid can also be used to prepare some drugs, such as vitamin C.
The method for preparing DL-2-Hydroxybutyric Acid is usually obtained by The hydration reaction of 2-butenedioic Acid. First, 2-butenedioic acid is dissolved in water, and then a certain amount of an acidic catalyst, such as sulfuric acid or phosphoric acid, is added to perform a heating reaction. After completion of the reaction, crystals of DL-2-Hydroxybutyric Acid are obtained by cooling crystallization or evaporation crystallization.
The security of DL-2-Hydroxybutyric Acid is higher. It is non-toxic and harmless under normal use conditions, and has no obvious irritation and corrosiveness. However, long-term heavy exposure may have negative effects on human health, such as causing gastrointestinal discomfort. Therefore, when using should follow the appropriate dosage and use recommendations, avoid excessive intake. During storage, it should be placed in a dry, cool, ventilated place to avoid contact with oxidants and strong acids and bases.
