Used primarily as an intermediate in organic synthesis, especially in the preparation of dyes and pigments due to its aromatic and conjugated structure. It also finds use in the development of photo-sensitive compounds and can act as a ligand in certain metal-catalyzed reactions. Its nitroso functionality allows for participation in cycloaddition reactions, making it valuable in the synthesis of heterocyclic compounds. Additionally, it has been explored in research settings for its potential in creating novel polymers with unique electronic properties.
