Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring halogenated aromatic structures. Its aldehyde and halogen functional groups allow for versatile chemical transformations, making it valuable in creating complex organic molecules. Commonly employed in cross-coupling reactions and as a building block in medicinal chemistry for designing drug candidates with enhanced metabolic stability and target specificity. Also utilized in the preparation of fluorescent probes and specialty materials where halogen substitution influences electronic properties.
