Used as an intermediate in the synthesis of fluorescent dyes and optical brighteners due to its ability to form complex structures with light-emitting properties. Commonly employed in the development of sensors for metal ion detection, especially for aluminum and zinc, leveraging its signaling capability upon binding. Also utilized in the preparation of specialty polymers and photoactive materials for use in electronic devices. Its bromine groups allow for further functionalization through cross-coupling reactions, making it valuable in organic synthesis and pharmaceutical research.
