Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of pyrazolone-based drugs with analgesic, anti-inflammatory, and antipyretic properties. It serves as a building block in the development of dyes and pigments due to its ability to form stable colored complexes. Also employed in agrochemicals for the formulation of certain pesticides and herbicides. Its reactivity makes it valuable in organic synthesis for constructing nitrogen-containing heterocycles. Additionally, it finds use in research laboratories for developing novel compounds in medicinal chemistry.
