Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Its halogenated aromatic structure makes it valuable in cross-coupling reactions, such as Suzuki and Heck reactions, to build complex molecules. Commonly employed in the development of bioactive compounds, including potential drug candidates with antitumor, anti-inflammatory, or antimicrobial activity. Also utilized in the preparation of fluorescent probes and functional materials due to its conjugated system and ease of derivatization.
