Used as an intermediate in the synthesis of fluorescent dyes and optical brighteners due to its reactive aromatic ring system and electron-withdrawing substituents. It is also employed in the development of agrochemicals, particularly as a building block for herbicides and fungicides. Its nitro and chloro groups allow for selective substitutions, making it valuable in pharmaceutical research for creating bioactive molecules. Additionally, it serves in the preparation of thiazole-based polymers with potential applications in organic electronics.
