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 biologically active molecules by serving as a building block for pyrimidine-based compounds. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of reactive sites that allow functionalization. Also utilized in agrochemical research for designing new crop protection agents. Its methylthio and ester groups enable diverse transformations, making it valuable in heterocyclic synthesis and drug discovery pipelines.
