Used primarily as an intermediate in the synthesis of dyes and pigments, this compound plays a key role in the development of azo dyes due to its amino and nitro functional groups, which allow for diazotization and coupling reactions. It is also employed in the production of certain pharmaceuticals, where it serves as a building block for more complex molecules with biological activity. Additionally, it finds use in research laboratories for the preparation of specialty chemicals and in the modification of polymers to enhance thermal and chemical resistance. Its ester group improves solubility in organic solvents, making it suitable for reactions in non-aqueous environments.
