Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the development of antihypertensive and anti-inflammatory agents. It serves as a building block for quinazoline-based drugs that target enzyme inhibition, such as tyrosine kinase inhibitors used in cancer therapy. Also employed in the preparation of central nervous system modulators due to its affinity for certain neurotransmitter receptors. Its structure supports the design of compounds with enhanced binding properties to biological targets, making it valuable in medicinal chemistry research and drug discovery.
