Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and anti-inflammatory agents. It serves as a building block in the preparation of quinazoline derivatives, which exhibit a range of biological activities including kinase inhibition and antimicrobial effects. Commonly employed in medicinal chemistry research for structure-activity relationship studies. Also utilized in agrochemicals for the development of herbicides and plant growth regulators due to its ability to modulate biological pathways in pests and weeds.
