Used primarily as an intermediate in organic synthesis, especially in the development of fluorescent dyes and sensors. Its structure supports conjugation and electron transfer, making it valuable in the preparation of compounds for bioimaging and molecular probes. Commonly employed in the synthesis of heterocyclic compounds with potential pharmaceutical activity, particularly in research targeting kinase inhibitors and antimicrobial agents. Also utilized in photochemical studies due to its nitro-aromatic and chromone-like features, which exhibit distinct UV-Vis absorption and emission properties under specific conditions.
