Used primarily as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for further functionalization through bromine displacement or nitro group reduction, enabling the construction of complex molecules. Commonly employed in the development of bioactive compounds due to the reactivity of the ester and nitro functionalities. Also utilized in photochemical studies where the nitroaryl group acts as a photolabile protecting group or photosensitizer.
