Used in pharmaceutical research as a key scaffold in the development of kinase inhibitors, particularly for targeting protein kinases involved in inflammatory diseases and cancer. Its structure supports high binding affinity to enzyme active sites, making it valuable in optimizing lead compounds for improved selectivity and potency. Also investigated for its potential in central nervous system agents due to its ability to cross the blood-brain barrier. Additionally, serves as a fluorescent probe in biochemical assays owing to its favorable photophysical properties.
