3-Mercaptoisobutyric acid

Description:

3-Mercaptoisobutyric acid, with the CAS number 26473-47-2, is an organic compound characterized by the presence of both a thiol (-SH) and a carboxylic acid (-COOH) functional group. This compound features a branched structure, which contributes to its unique chemical properties. It is typically a colorless to pale yellow liquid or solid, depending on the temperature and purity. The thiol group imparts strong reducing properties, making it reactive with various electrophiles and capable of forming disulfide bonds. Additionally, the carboxylic acid group allows for acidic behavior, enabling it to participate in acid-base reactions. 3-Mercaptoisobutyric acid is soluble in water and organic solvents, which enhances its utility in various applications, including pharmaceuticals, agrochemicals, and as a chemical intermediate in organic synthesis. Its reactivity and functional groups make it valuable in the development of new materials and in biochemical research, particularly in studies involving thiol chemistry and protein interactions. Safety precautions should be observed when handling this compound due to its potential toxicity and reactivity.
