Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antitubercular and antifungal agents. Its hydrazide functionality allows for the formation of Schiff bases, which are important in medicinal chemistry for their biological activity. Also employed in the preparation of coordination compounds and metal-organic frameworks due to its ability to chelate metal ions. Finds application in analytical chemistry as a derivatizing agent for the detection of carbonyl compounds. Additionally, it serves as a building block in the synthesis of heterocyclic compounds such as oxadiazoles and triazoles, which are prevalent in agrochemicals and dyes.
