Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of indigo derivatives for textile coloring. Also employed in the development of organic semiconductors and photoconductive materials for use in electronic devices such as OLEDs and photocopiers. Its nitro group facilitates further chemical modifications, making it valuable in pharmaceutical research for building complex heterocyclic compounds. Additionally, it serves as a precursor in the preparation of carbazole-based antioxidants and corrosion inhibitors.
