Used in pharmaceutical development as a key scaffold for designing bioactive molecules, including kinase inhibitors, anti-inflammatory agents, and central nervous system drugs for conditions like Alzheimer's and Parkinson's disease. Its derivatives exhibit antimicrobial, antiviral, and anticancer activities through interactions with enzymes and receptors in biological systems. Also applied in agrochemicals for synthesizing fungicides and plant growth regulators. Fluorescence properties enable its use in sensors and imaging probes for detecting metal ions or biomolecules. Additionally, its structure supports applications in organic electronics research as a conductor or sensor component. Widely utilized in structure-activity relationship studies for drug discovery.
