Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in creating complex heterocyclic systems found in drug candidates. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to build carbon-carbon bonds in medicinal chemistry. Also utilized in the preparation of agrochemicals and functional materials due to its reactivity and ability to serve as a building block in multistep organic syntheses.
