Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its reactive bromomethyl group allows for easy coupling with nucleophiles, making it valuable in constructing complex heterocyclic systems. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) where the pyrimidine scaffold is essential. Also utilized in agrochemicals for the creation of novel pesticides due to its ability to modify bioactive molecules. Its versatility in cross-coupling reactions enhances its role in medicinal chemistry research and development.
