Application

Quinolin-5-ylboronic acid is widely used in palladium-catalyzed cross-coupling reactions to form biaryl compounds, a key step in drug discovery and material science. It serves as a critical intermediate in the synthesis of quinoline-based pharmaceuticals, including kinase inhibitors and antimicrobial agents. Researchers also employ it in the development of fluorescent probes and organic electronic materials due to its conjugated aromatic system.
