Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports the construction of pyrimidine-based drug candidates, which are common in treatments for cancer, inflammatory diseases, and viral infections. Also employed in agrochemical research for designing novel pesticides and herbicides due to its ability to interact with biological targets in pests and weeds. Commonly utilized in medicinal chemistry for scaffold modification and structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
