Used as a key intermediate in the synthesis of functional dyes and pigments, particularly in the production of high-performance azo dyes for textiles and inks. It is also employed in the development of photographic chemicals and electroactive materials due to its redox-active aromatic amine structure. Its electron-donating methoxy and amine groups make it suitable for use in organic semiconductors and conductive polymers. Additionally, it serves as a building block in the preparation of certain pharmaceuticals and agrochemicals where substituted phenylenediamine derivatives are required.
