Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinamide-based drugs and kinase inhibitors. Its structure supports the creation of bioactive molecules with potential applications in treating inflammatory diseases and certain cancers. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the versatility of the pyridine core and the reactive ester group. Also utilized in agrochemical research for designing new pesticides and plant growth regulators. The methylthio moiety allows further functionalization, enabling the introduction of sulfur-containing groups in target compounds.
