Used as an intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals, particularly in the preparation of heterocyclic compounds such as indoles and pyrazoles. Its fluorinated aromatic structure enhances binding selectivity and metabolic stability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies involving nitrogen-containing rings. Also utilized in the development of dyes and fluorescent probes due to the electron-withdrawing effect of fluorine atoms, which can tune optical properties.
