Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinamide derivatives and vitamin B3 analogs. Serves as a catalyst or reagent in organic synthesis due to its acidic properties and pyridine ring structure. Employed in electroplating baths to improve metal deposition efficiency and surface finish. Acts as a stabilizer in some polymer systems, enhancing thermal resistance. Also utilized in the development of coordination compounds for catalytic applications in industrial chemistry.
