Used primarily as an intermediate in the synthesis of advanced agrochemicals and pharmaceuticals. Its chlorinated structure enhances reactivity in cross-coupling reactions, making it valuable in the development of herbicides and fungicides. Also employed in the production of specialty polymers where thermal stability and chemical resistance are required. Due to its lipophilic nature, it has been explored in transdermal drug delivery systems as a permeation enhancer. Limited use in industrial applications due to environmental persistence concerns.
