Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Shows potential in medicinal chemistry for designing drugs targeting inflammatory diseases and central nervous system disorders due to its ability to cross the blood-brain barrier. Also employed in the creation of fluorescent probes for biochemical assays, leveraging its photophysical properties. Its scaffold is explored in structure-activity relationship (SAR) studies to enhance drug potency and selectivity.
