Used primarily as an intermediate in organic synthesis, especially in the preparation of heterocyclic compounds. It serves as a building block in the development of pharmaceuticals, including antimicrobial and anti-inflammatory agents. Its hydrazide functionality allows it to act as a precursor in the formation of acyl hydrazones, which are studied for their biological activity. Also employed in the synthesis of agrochemicals and dyes due to its reactive structure and ability to form stable derivatives.
