Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of nicotinamide-based drugs targeting metabolic and neurological disorders. It serves as a building block in medicinal chemistry for creating analogs with potential enzyme inhibitory activity. Also employed in research settings to study structure-activity relationships in nicotinic receptor ligands. Its chloro and methyl functional groups allow for selective modifications, making it valuable in optimizing drug candidates for improved bioavailability and target specificity.
