Used primarily as an intermediate in the synthesis of heterocyclic compounds, especially in the preparation of dyes and pigments. It serves as a building block in the production of azo dyes, which are widely used in the textile, printing, and coating industries due to their vibrant colors and stability. Also employed in the development of pharmaceuticals, where it participates in the formation of biologically active molecules, including certain anti-inflammatory and antimicrobial agents. Its nitro and hydrazine functional groups make it valuable in coupling reactions and the construction of nitrogen-containing rings such as pyrazoles and indazoles. Additionally, it finds use in research laboratories for the development of novel organic compounds and in the design of sensors or functional materials where specific molecular recognition is required.
