Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its ability to form stable complexes with metal ions. Its bromine and amino functional groups allow for selective chemical modifications, making it valuable in the development of sensors for detecting metal ions in environmental monitoring. Also employed in the preparation of specialty polymers with enhanced thermal and photochemical stability. Additionally, it serves as a building block in the creation of contrast agents for medical imaging, where its structure supports strong X-ray absorption.
