Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system agents and anti-inflammatory drugs. Its functional groups allow for selective modifications, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of benzodiazepine derivatives and other heterocyclic compounds through alkylation or coupling reactions. Also utilized in agrochemical research for designing novel pesticides due to its halogenated aromatic structure, which enhances bioavailability and binding affinity.
