Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of isoquinoline-based compounds with biological activity. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to form carbon-carbon bonds. Applied in research for developing kinase inhibitors and other bioactive molecules. Also utilized in the synthesis of fluorescent dyes and materials for optoelectronic devices due to the aromatic structure's electron-transport properties.
