Acetoin

Description:

Acetoin, also known as 3-hydroxybutan-2-one, is an organic compound with the chemical formula C4H8O2. It is a colorless to pale yellow liquid with a characteristic buttery aroma, often associated with fermented products. Acetoin is a ketone and a dihydroxy compound, featuring both a hydroxyl group and a carbonyl group in its structure. It is soluble in water and organic solvents, making it versatile for various applications. Acetoin is commonly used as a flavoring agent in the food industry, particularly in dairy products and baked goods, due to its pleasant taste and aroma. Additionally, it serves as an intermediate in the synthesis of other chemicals and is utilized in the production of certain pharmaceuticals and cosmetics. In terms of safety, acetoin is generally recognized as safe when used in food, but like many chemicals, it should be handled with care to avoid potential health risks associated with inhalation or skin contact.

3-Hydroxy-2-butanone

CAS: 513-86-0

3-Hydroxy-2-butanone is a reactive, fatty acid with the chemical formula CH3(CH2)4COH. It is a methyl ketone and an important intermediate in the synthesis of other organic compounds. 3-Hydroxy-2-butanone can be produced by corynebacterium glutamicum through the addition of air to a mixture of 2-butanol and malonic acid. This compound has inhibitory properties against wild type strains of corynebacterium glutamicum and caproic acid production by tissue culture cells. The mechanism for this inhibition is not yet known, but it may be due to its ability to alter the biochemical properties of corynebacterium glutamicum.
