Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of kinase inhibitors and other biologically active compounds. Its aldehyde and nitrile functional groups allow for versatile chemical transformations, enabling the construction of complex molecules in drug development. Commonly employed in cross-coupling reactions, condensations, and heterocycle formation to build fluorinated aromatic scaffolds with enhanced metabolic stability and binding affinity. Also applied in the preparation of agrochemicals and functional materials where fluorine substitution improves performance.
