Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. It is also employed in agrochemical research for designing novel pesticides and herbicides due to its electron-deficient aromatic core, which enhances binding to biological targets. The presence of chlorine and nitro groups facilitates cross-coupling reactions and nucleophilic substitutions, enabling diverse derivatization pathways in drug discovery and process chemistry.
