Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its electrophilic aromatic ring system allows for selective substitutions, making it valuable in medicinal chemistry for constructing complex heterocyclic compounds. Commonly employed in research settings to design potential anticancer, anti-inflammatory, and antimicrobial agents. Also utilized in agrochemical research for developing novel pesticides due to its reactive chlorine and nitro groups that can be modified to enhance biological activity.
