Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals and dyes. Its nitroso and amino functional groups make it valuable in coupling reactions and heterocyclic compound formation. It also shows potential in research related to UV absorbers and photostabilizers due to its ability to undergo tautomerism and absorb specific wavelengths of light. Additionally, it has been studied for its role in the synthesis of bioactive molecules with possible antiviral or anticancer properties.
