Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anticonvulsant and anti-inflammatory agents. It serves as a building block in medicinal chemistry due to its ability to interact with biological targets through hydrogen bonding and aromatic interactions. Also employed in the preparation of agrochemicals and dyes, where its chlorinated heterocyclic structure enhances reactivity and stability. Its derivatives are explored in research for potential bioactive properties, including antimicrobial and antitumor activities.
