3-Methyl-2-butenoic acid

Description:
3-Methyl-2-butenoic acid, also known as isovaleryl acid, is an unsaturated carboxylic acid characterized by its branched structure. It features a double bond between the second and third carbon atoms in its carbon chain, which contributes to its reactivity and potential applications in organic synthesis. The presence of the carboxylic acid functional group (-COOH) imparts acidic properties, allowing it to participate in various chemical reactions, such as esterification and amidation. This compound is typically a colorless liquid with a distinctive odor, and it is soluble in polar solvents like water due to its ability to form hydrogen bonds. Its molecular formula is C5H8O2, and it has a relatively low boiling point compared to saturated carboxylic acids of similar molecular weight. 3-Methyl-2-butenoic acid is used in the production of various chemical intermediates and can also serve as a building block in the synthesis of more complex organic molecules. Safety precautions should be observed when handling this compound, as it may cause irritation to the skin and eyes.
