Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its amine and phenolic functional groups allow for versatile chemical modifications, making it suitable for developing bioactive molecules. Commonly employed in the synthesis of fluorescent probes and dyes due to its ability to form conjugated systems. Also utilized in the development of polymer additives and cross-linking agents, where its reactivity enhances material stability. Its hydrobromide salt form improves solubility and handling in aqueous reaction systems.
