Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and antitumor compounds. Its structure enables selective modification for targeted drug design. Commonly employed in research settings to construct quinazoline-based bioactive molecules with potential anticancer, anti-inflammatory, and antimicrobial properties. Also utilized in agrochemical research for developing novel pesticides due to its ability to modulate enzyme activity in pests. Its reactivity allows for efficient coupling in heterocyclic chemistry, making it valuable in medicinal chemistry workflows.
