3butenamide

3-Butenamide is an organic compound with the chemical formula C4H7NO. It is an unsaturated amide, meaning it contains a carbon-carbon double bond and an amide functional group. The double bond is located between the third and fourth carbon atoms, hence the "3-buten" prefix. The "amide" suffix indicates the presence of the -CONH2 group.

This compound is a derivative of butenoic acid. It can exist as cis or trans isomers due to the presence of the double bond, although the trans isomer is generally more stable. 3-Butenamide can be synthesized through various chemical reactions, including the amidation of 3-butenoic acid or its derivatives.

The properties of 3-butenamide are influenced by both the double bond and the amide group. The double bond makes it susceptible to addition reactions, while the amide group can participate in hydrogen bonding and other characteristic reactions of amides. Its physical state is typically a solid at room temperature, with a melting point that can vary depending on its purity and isomeric form. 3-Butenamide finds limited direct applications but serves as a potential intermediate in the synthesis of more complex organic molecules. Research into its reactivity and potential uses in polymer chemistry or as a building block for pharmaceuticals is ongoing.
