(2E)-3-(4-Chlorophenyl)-2-propenoic acid

Description:

(2E)-3-(4-Chlorophenyl)-2-propenoic acid, commonly known as 4-chlorocinnamic acid, is an organic compound characterized by its unsaturated carboxylic acid structure. It features a trans configuration (denoted by 2E) around the double bond between the second and third carbon atoms. The presence of a chlorophenyl group at the third carbon contributes to its aromatic properties and influences its reactivity and solubility. This compound typically appears as a white to pale yellow crystalline solid and is sparingly soluble in water but more soluble in organic solvents such as ethanol and acetone. It exhibits interesting chemical behavior, including the ability to undergo various reactions such as Michael addition and Diels-Alder reactions, making it valuable in organic synthesis. Additionally, 4-chlorocinnamic acid has been studied for its potential biological activities, including anti-inflammatory and antimicrobial properties. Its unique structure and functional groups make it a subject of interest in both synthetic and medicinal chemistry.
