Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinamide derivatives and vitamin B3 analogs. Plays a role in the preparation of ligands for catalytic processes, especially in coordination chemistry with transition metals. Employed in the development of fluorescent probes and sensors due to its ability to form conjugated systems upon condensation reactions. Also utilized in agrochemical synthesis for creating herbicides and plant growth regulators. Its reactivity makes it suitable for use in multicomponent reactions to build nitrogen-containing heterocycles.
