Usage

Description

(E)-2,3-dichloro-1,1,1,4,4,4-hexafluoro-but-2-ene, commonly known as HCFC-131a, is a colorless, flammable gas that belongs to the hydrochlorofluorocarbons (HCFCs) family. It is primarily used as a refrigerant and foam blowing agent due to its low global warming potential, making it a suitable alternative to other ozone-depleting substances in certain applications. However, it is classified as an ozone-depleting substance and is being phased out under the Montreal Protocol. Careful handling and disposal are essential to minimize its environmental impact.
