Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of phenoxazine-based colorants for textiles and polymers. Serves as a building block in pharmaceutical research for developing compounds with biological activity, including antimicrobial and antitumor agents. Employed in organic electronics due to its electron-donating properties, making it suitable for use in fluorescent probes and optoelectronic materials. Also utilized in the development of sensors and imaging agents in analytical chemistry.
