Description

1,2-Dibromotetrafluoroethane (CAS No. 124-73-2), also known as 1,2-dibromo-1,1,2,2-tetrafluoroethane, is a high-purity halogenated hydrocarbon with the molecular formula C₂Br₂F₄. This colorless to pale yellow liquid is characterized by its exceptional thermal stability and non-flammability, making it a valuable reagent in specialized chemical syntheses and industrial applications. With a boiling point of approximately 47.3°C and a density of 2.18 g/cm³, it is particularly useful as a solvent, intermediate, or fire suppressant in demanding environments. Its unique tetrafluoroethane backbone coupled with bromine substituents provides excellent reactivity for halogen exchange reactions and as a precursor in fluoropolymer production. Packaged under inert gas to ensure stability, our product is available in various quantities with ≥98% purity (GC) and is supplied with comprehensive analytical documentation including GC-MS and NMR data.

Application

1,2-Dibromotetrafluoroethane serves as a critical intermediate in the synthesis of fluorinated organic compounds and specialty polymers. It is employed as a fire-extinguishing agent in high-value equipment protection systems due to its non-conductive and non-corrosive properties. The compound also finds use as a solvent in precision cleaning applications for optical and electronic components where residue-free performance is essential. Researchers utilize it as a brominating agent in organofluorine chemistry and as a building block for pharmaceutical and agrochemical active ingredients. Its thermal stability makes it suitable for high-temperature reactions in closed systems.
