Used in organic synthesis and pharmaceutical research, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl compounds. Its boronic acid functionality allows for efficient carbon-carbon bond formation, making it valuable in the development of nitrogen-containing heterocyclic systems. Commonly applied in the synthesis of potential drug candidates targeting neurological disorders and cancer due to the isoquinoline scaffold’s biological relevance. Also employed in materials science for creating fluorescent probes and organic electronic materials.
