Used in pharmaceutical research as a key intermediate in the synthesis of bioactive quinazoline derivatives. Shows potential in the development of kinase inhibitors, which are explored for anticancer therapies. Also utilized in studies related to central nervous system agents due to its structural affinity with neurotransmitter receptors. Its derivatives are investigated for anti-inflammatory, antiviral, and antihypertensive activities. Commonly employed in structure-activity relationship (SAR) studies to optimize drug candidates targeting tyrosine kinases and other enzyme systems.
