Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring halogenated aromatic scaffolds. Its aldehyde and nitrile functional groups allow for versatile chemical transformations, such as condensation reactions and nucleophilic substitutions, making it valuable in constructing heterocyclic compounds. Commonly employed in the preparation of kinase inhibitors and other biologically active molecules in medicinal chemistry research. Also utilized in the fabrication of organic semiconductors and fluorescent dyes due to its electron-withdrawing groups and aromatic structure.
