2-Pentenoic acid, with the CAS number 626-98-2, is an unsaturated carboxylic acid characterized by a five-carbon chain featuring a double bond between the second and third carbon atoms. This compound has a molecular formula of C5H8O2 and is known for its distinctive odor, which can be described as pungent or fatty. The presence of the double bond contributes to its reactivity, making it susceptible to various chemical reactions, such as hydrogenation and polymerization. 2-Pentenoic acid is typically a colorless to pale yellow liquid at room temperature and has a relatively low boiling point compared to saturated carboxylic acids of similar chain length. It is soluble in organic solvents and exhibits moderate solubility in water due to the presence of the carboxylic acid functional group. This compound is utilized in organic synthesis and can serve as an intermediate in the production of various chemicals, including pharmaceuticals and agrochemicals. Safety precautions should be taken when handling this substance, as it may cause irritation to the skin and eyes.
