Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of central nervous system agents and anti-inflammatory compounds. Shows potential in the design of selective enzyme inhibitors due to its structural affinity for certain kinase enzymes. Also employed in the study of isoquinoline-based derivatives for anticancer activity, where it serves as a scaffold to enhance metabolic stability and binding specificity. Its derivatives are explored for their antimicrobial properties, making it valuable in medicinal chemistry for lead optimization.
