Used as an intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of oxadiazoles and other nitrogen-containing rings which exhibit biological activity. Commonly applied in medicinal chemistry for developing antimicrobial, anti-inflammatory, and antitubercular agents. Also utilized in the design of hydrazide-based inhibitors targeting specific enzymes due to its ability to form stable conjugates. Its aromatic and polar functional groups make it suitable for enhancing binding affinity in drug design.
