Used as an intermediate in organic synthesis, particularly in the preparation of dyes and pigments. It plays a role in the development of azo dyes due to its nitro and aromatic amine functionalities, which are key in diazotization and coupling reactions. Also employed in the synthesis of certain pharmaceuticals and agrochemicals where nitroaromatic compounds serve as precursors for further functionalization. Its ethoxycarbonyl group aids in protecting the amine during multi-step reactions, allowing selective transformations.
