2-Butenoic acid, 4-chloro-, (2E)-

Description:
2-Butenoic acid, 4-chloro-, (2E)-, also known as 4-chloro-2-butenoic acid, is an organic compound characterized by its unsaturated carboxylic acid structure. It features a double bond between the second and third carbon atoms in the butenoic acid chain, with a chlorine substituent at the fourth carbon position. This compound is typically a colorless to pale yellow liquid with a pungent odor. It is soluble in polar solvents such as water and alcohols, owing to the presence of the carboxylic acid functional group, which can engage in hydrogen bonding. The (2E) designation indicates the specific geometric configuration of the double bond, which is crucial for its reactivity and interactions in chemical reactions. 2-Butenoic acid, 4-chloro-, is used in various chemical syntheses and may serve as an intermediate in the production of pharmaceuticals and agrochemicals. As with many chlorinated compounds, it is important to handle this substance with care due to potential toxicity and environmental concerns.
