Used primarily as an intermediate in the synthesis of dyes and pharmaceuticals. It plays a key role in the preparation of certain sulfa drugs due to its reactive sulfonamide and nitro groups. The compound is also utilized in the development of agrochemicals, particularly as a building block for herbicides and pesticides. Its chloro and nitro functionalities allow for further chemical modifications, making it valuable in organic synthesis and research laboratories for creating more complex molecules. Additionally, it has been explored in the production of fluorescent probes and sensors due to its electron-withdrawing properties.
