3-(2,3-Difluorophenyl)-2-propenoic acid, with the CAS number 207981-48-4, is an organic compound characterized by its propenoic acid structure, which features a double bond between the second and third carbon atoms of the propene chain. The presence of a 2,3-difluorophenyl group indicates that two fluorine atoms are substituted on the phenyl ring, specifically at the second and third positions, which can significantly influence the compound's chemical reactivity and physical properties. This substitution can enhance the compound's lipophilicity and alter its electronic characteristics, potentially affecting its interactions in biological systems. The compound is likely to exhibit acidic behavior due to the carboxylic acid functional group (-COOH), which can donate protons in solution. Additionally, the presence of fluorine atoms may impart unique properties such as increased stability and altered solubility compared to non-fluorinated analogs. Overall, this compound may have applications in pharmaceuticals or materials science, where fluorinated compounds are often sought for their distinctive properties.
