Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of benzodiazepine derivatives with potential anxiolytic and anticonvulsant properties. It serves as a building block in heterocyclic chemistry, enabling the construction of fused ring systems important in medicinal research. Its nitro group allows for further functionalization, making it valuable in creating diverse compound libraries for drug discovery. Also applied in the preparation of fluorescent probes and dyes due to its aromatic and electron-deficient structure.
