Used primarily as an intermediate in the synthesis of fluorinated compounds, especially in the production of hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs) that serve as environmentally friendly refrigerants. It plays a key role in replacing ozone-depleting substances due to its utility in generating chlorine-free end products. Additionally, it functions as a solvent and a chlorinating agent in select organic reactions, valued for its stability and reactivity profile in industrial processes. Its application is largely confined to specialized chemical manufacturing rather than consumer products.
