Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for antiviral and anticancer agents. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic compounds. Commonly employed in agrochemical research for designing new pesticides and herbicides due to its reactivity and stability in multi-step reactions. Also utilized in the preparation of fluorescent dyes and sensors, where the chloro and nitro groups facilitate further substitution and signal detection.
