Used in pharmaceutical research as an intermediate in the synthesis of bioactive molecules, particularly in the development of kinase inhibitors and anticancer agents. Shows potential in the design of compounds targeting neurological disorders due to its affinity for certain CNS receptors. Also employed in the study of anti-inflammatory pathways, where its derivatives demonstrate modulatory effects on cytokine production. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving isoquinoline-based therapeutics.
