Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports the formation of biologically active molecules by serving as a building block in heterocyclic chemistry. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance binding affinity and selectivity in drug candidates. Also utilized in agrochemical research for designing new pesticides and herbicides, where the methylthio and amino groups contribute to improved stability and biological activity.
