Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its ability to enhance light emission in specific wavelength ranges. Commonly applied in the development of sensors for metal ion detection, especially for copper and mercury in environmental samples. Also utilized in pharmaceutical research for building blocks in heterocyclic compounds with potential biological activity. Its bromine functionality allows for easy coupling reactions in organic synthesis, particularly in Suzuki and Heck reactions, making it valuable in material science and drug discovery.
