Chemical Structure
Basic Info
2,3-Butanedione (C₄H₆O₂) is an organic compound belonging to the diketone class. It is a yellow to green liquid at room temperature with a strong creamy aroma. It is widely used in the food, flavor and cosmetic industries as a flavor enhancer. Among chemical raw materials, 2,3-butanedione is mainly prepared by the oxidation reaction of butanediol, and commonly used oxidants include sodium dichromate or oxygen. In addition, it can also be produced by microbial fermentation or pyrolysis of certain carbohydrates. 2,3-Butanedione is not only an important flavor, but also an intermediate in organic synthesis for the preparation of heterocyclic compounds and drugs. Due to its high volatility, ventilation and fire prevention should be paid attention to during storage and use.
