Used primarily as an intermediate in the synthesis of herbicides, particularly in the production of selective chloroacetanilide-type herbicides that control weeds in crops like corn and soybeans. It serves as a key building block in agrochemical manufacturing due to its ability to form stable derivatives with herbicidal activity. Also employed in the development of specialty polymers and flame retardants where chlorinated aromatic structures enhance thermal stability and resistance to degradation. Its rigid molecular structure makes it suitable for advanced material applications requiring high performance under extreme conditions.
