Used as an intermediate in the synthesis of fluorescent dyes and biologically active compounds. It plays a role in the development of optical brighteners and sensors due to its electron-withdrawing nitro group and conjugated structure. Also employed in research for developing new heterocyclic compounds with potential pharmaceutical applications, particularly in antimicrobial and antitumor agent design. Its reactivity allows for further functionalization in organic synthesis, making it valuable in medicinal chemistry and materials science.
