6-Bromochromone is primarily used as an intermediate in organic synthesis, especially in the development of biologically active compounds. It serves as a building block in the preparation of flavonoid derivatives, which are known for their antioxidant, anti-inflammatory, and anticancer properties. Its bromine functionality allows for further chemical modifications through cross-coupling reactions, making it valuable in pharmaceutical research and drug discovery. It is also employed in the synthesis of fluorescent probes and heterocyclic compounds used in materials science and medicinal chemistry.
