Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated drug candidates where the fluorine atoms enhance metabolic stability and bioavailability. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) for central nervous system agents and anti-inflammatory compounds. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its ability to improve lipophilicity and membrane permeability in target molecules. Serves as a building block in medicinal chemistry for structure-activity relationship (SAR) studies involving aromatic carboxylic acids.
