Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Shows potential in the development of kinase inhibitors and other therapeutic agents targeting neurological disorders and cancer. Also employed in research settings to design fluorescent probes due to its heterocyclic structure with inherent photophysical properties. Its derivatives are explored for antimicrobial and anti-inflammatory activities. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving isoquinoline-based molecules.
