Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly in the development of central nervous system agents and kinase inhibitors. Shows potential in the design of novel therapeutics targeting neurological disorders due to its structural affinity with isoquinoline-based neurotransmitters. Also employed in the preparation of fluorescent probes for biochemical assays, leveraging its luminescent properties when derivatized. Its amine functionality allows for easy conjugation, making it valuable in medicinal chemistry for structure-activity relationship studies.
