3butenoic

3butenoic is a chemical compound with the molecular formula C4H6O2. It is an unsaturated carboxylic acid, meaning it contains a carbon-carbon double bond and a carboxyl group. The double bond is located between the third and fourth carbon atoms in the four-carbon chain, hence the name "3butenoic." It is also known as vinylacetic acid. Structurally, it can be represented as CH2=CHCH2COOH.

3butenoic acid is a colorless liquid at room temperature. It is soluble in water and many organic solvents. Due to the presence of both a double bond and a carboxylic acid functional group, it can undergo a variety of chemical reactions. The double bond allows for addition reactions, such as hydrogenation or halogenation, while the carboxyl group can participate in esterification, salt formation, and amide formation.

This compound can be synthesized through various methods, often involving reactions that introduce or manipulate the double bond and carboxyl group. Its applications are generally related to its reactive functional groups, serving as a building block or intermediate in the synthesis of other organic compounds, polymers, or specialty chemicals. Research into its properties and applications continues in various fields of organic chemistry.
