Used in the synthesis of pharmaceutical intermediates, particularly in the development of antiviral and anticancer agents. Its structure serves as a key scaffold in medicinal chemistry for designing inhibitors targeting specific enzymes involved in disease pathways. Commonly utilized in research settings to explore new drug candidates due to its ability to interact with biological targets such as kinases and nucleic acids. Also employed in the preparation of fluorescent probes for biochemical assays owing to its favorable photophysical properties.
