Used in the synthesis of pharmaceutical intermediates, particularly in the development of compounds with potential biological activity. Its structure features a 3,4-diaminophenyl group attached to an ethyl acetate moiety, with aromatic amine groups that facilitate condensation, coupling, and other reactions. This makes it valuable in the preparation of dyes, heterocyclic compounds, and active pharmaceutical ingredients. Commonly employed in research settings for designing novel molecules in medicinal chemistry.
