Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. Shows activity in modulating signaling pathways involved in cell proliferation and apoptosis. Investigated for potential use in treating solid tumors due to its ability to cross cell membranes and bind selectively to ATP-binding sites in specific kinases. Also employed in the development of fluorescent probes for biochemical assays because of its conjugated structure and favorable emission properties.
