Also employed in the production of other chlorinated compounds and as an intermediate in chemical synthesis. Found in some paint and varnish removers due to its effectiveness in breaking down tough coatings. Limited use in pesticide formulations and as a fumigant in specific agricultural applications. Its application has declined due to toxicity and environmental concerns, leading to substitution with safer alternatives where possible.
