Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure allows for easy functionalization, making it valuable in building more complex heterocyclic compounds. Commonly employed in medicinal chemistry for constructing pyrimidine-based drug candidates. Also utilized in agrochemical research for developing new pesticides and herbicides due to its reactive scaffold. Frequently appears in kinase inhibitor designs, where the bromo and amino groups enable selective cross-coupling and substitution reactions.
