Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs with biological activity such as antimicrobial and anti-inflammatory agents. It serves as a building block in organic synthesis due to the presence of both ester and nitro functional groups, which can be selectively modified. Commonly employed in the preparation of thiophene-based compounds for research in medicinal chemistry and drug discovery. Also utilized in the production of agrochemicals and functional materials where aromatic heterocycles are required.
