(2E)-4-chlorobut-2-enoic acid, 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, with a chlorine substituent at the fourth carbon. This compound is typically a colorless to pale yellow liquid and is soluble in polar solvents due to the presence of the carboxylic acid functional group. Its molecular structure contributes to its reactivity, making it a potential intermediate in organic synthesis, particularly in the production of various pharmaceuticals and agrochemicals. The presence of the chlorine atom enhances its electrophilic character, allowing it to participate in nucleophilic substitution reactions. Additionally, (2E)-4-chlorobut-2-enoic acid can exhibit isomerism, with the (E) configuration indicating the relative positioning of substituents around the double bond. Safety precautions should be taken when handling this compound, as it may pose health risks, including irritation to the skin and respiratory system.
