5-Quinolineboronic Acid Pinacol Ester is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This chemical serves as a key intermediate for constructing complex quinoline derivatives, which are valuable in pharmaceutical research. It is employed in the development of drug candidates, especially for targeting diseases like cancer and infections, due to the biological activity of quinoline-based compounds. Additionally, it is utilized in material science for creating organic electronic materials and ligands in catalysis. Its stability and reactivity make it a preferred choice for building diverse molecular architectures.
