Used in organic synthesis as a building block for pharmaceuticals and agrochemicals. Its fluorinated aromatic structure makes it valuable in the development of bioactive molecules, particularly in medicinal chemistry for designing kinase inhibitors and central nervous system agents. Commonly employed in cross-coupling reactions and condensation processes to construct nitrogen-containing heterocycles. Also utilized in the preparation of fluorescent probes and functional materials due to its electron-withdrawing fluorine substituent and reactive aldehyde group.
