Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals, 4-Chloro-m-xylene serves as a building block for more complex organic molecules. Its reactivity allows for further functionalization in the production of herbicides and plant growth regulators. It is also employed in the manufacture of dyes and specialty polymers due to its stable aromatic structure and chlorine substituent, which facilitates coupling reactions. In research laboratories, it acts as a solvent and reagent in organic transformations, particularly in cross-coupling and halogenation processes.
