2-Ethyl-4-pentenoic acid is an organic compound characterized by its unsaturated carboxylic acid structure. It features a five-carbon chain with a double bond located between the fourth and fifth carbon atoms, and an ethyl group attached to the second carbon. This configuration contributes to its reactivity, particularly in addition reactions typical of alkenes. The presence of the carboxylic acid functional group (-COOH) imparts acidic properties, allowing it to participate in various chemical reactions, including esterification and amidation. The compound is typically a colorless to pale yellow liquid with a distinctive odor. It is soluble in organic solvents and exhibits moderate solubility in water. 2-Ethyl-4-pentenoic acid is utilized in the synthesis of various chemical intermediates and can serve as a building block in the production of polymers and other materials. Safety data indicates that, like many organic acids, it should be handled with care to avoid skin and eye irritation.
