Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the creation of compounds that interact with biological targets such as kinases and viral enzymes. Also employed in research for designing new bioactive molecules due to its electron-deficient aromatic core, which enhances binding to biomolecules. Additionally, it serves in the preparation of fluorescent dyes and sensors owing to its favorable photophysical properties.
