Used as an intermediate in the synthesis of pharmaceutical agents, particularly in the development of antihypertensive and anti-inflammatory drugs. It serves as a building block for quinazoline-based compounds that exhibit kinase inhibition activity, making it valuable in research for anticancer agents. Also employed in the preparation of derivatives for studying structure-activity relationships in central nervous system depressants. Its scaffold is explored in medicinal chemistry for optimizing drug candidates with improved metabolic stability and binding affinity.
