Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective substitution reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. It is also employed in research settings to design compounds with potential anticancer and antimicrobial properties. Due to the presence of reactive chlorine atoms and a nitro group, it serves as a versatile building block in cross-coupling and nucleophilic aromatic substitution reactions.
