Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeting protein kinases involved in cancer cell proliferation. Shows potential in developing antitumor agents due to its ability to modulate signaling pathways. Also employed in the design of fluorescent probes for biochemical assays, leveraging its conjugated structure for detection in cellular imaging. Investigated for use in neuroprotective agents owing to structural similarity with indole-based neurotransmitters.
