3-Methylisoxazole-4-carboxylic acid

Description:

3-Methylisoxazole-4-carboxylic acid is an organic compound characterized by its isoxazole ring structure, which features a five-membered ring containing three carbon atoms, one nitrogen atom, and one oxygen atom. The presence of a carboxylic acid functional group (-COOH) at the 4-position and a methyl group (-CH3) at the 3-position contributes to its unique chemical properties. This compound is typically a white to off-white solid and is soluble in polar solvents such as water and alcohols, owing to its polar functional groups. It exhibits acidic behavior due to the carboxylic acid group, allowing it to participate in various chemical reactions, including esterification and amidation. 3-Methylisoxazole-4-carboxylic acid is of interest in medicinal chemistry and may serve as a building block for the synthesis of pharmaceuticals or agrochemicals. Its biological activity and potential applications are subjects of ongoing research, making it a compound of interest in both academic and industrial settings.

Methylisoxazole-4-carboxylic acid

CAS: 17153-20-7

Methylisoxazole-4-carboxylic acid is an amide that is oxidized to form a hydroxycrotonic acid. It is found in food products, such as milk and eggs, which are rich in amino acids. Methylisoxazole-4-carboxylic acid can be converted to the corresponding hydroxycrotonic acid by deamination of alpha-ketoglutarate or by enamine formation with other amines. These processes are important for the metabolism of amino acids and the synthesis of proteins. Methylisoxazole-4-carboxylic acid has analgesic properties and has been shown to reduce cycloaddition reactions that lead to the formation of free radicals. The methyl group on this compound also allows it to act as a reducing agent, forming nitro compounds with nitrous oxide or nitric oxide and hydroxyl groups with alcohols, phenols, and pyridines.
