Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals, this compound serves as a building block in the construction of complex heterocyclic systems. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the introduction of various substituents for drug development. It is also employed in the preparation of kinase inhibitors and other biologically active molecules due to the quinoline core’s prevalence in medicinal chemistry. Additionally, it finds use in materials science for designing organic semiconductors and fluorescent probes, leveraging the electron-rich aromatic structure.
