Used primarily as an intermediate in the synthesis of fluorocarbons, including hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) for refrigerants, though production has decreased due to ozone depletion concerns. It serves in the production of high-performance polymers and specialty chemicals. Also employed in the manufacture of pesticides and agrochemicals due to its reactivity in halogen exchange reactions. Limited use in laboratories for organic synthesis where chlorinated olefins are required. Not commonly used as a solvent. Handling requires caution due to toxicity and environmental persistence.
