Methyl triphenyl phosphonium bromide CAS No 1779-49-3

Phase Transfer Catalyst Methyl triphenylphosphine bromide cas:1779-49-3 is an organic compound with the chemical formula C19H18PBr. It is a white powder and a solid Quaternary Phosphonium Salt flame retardant. Halogen containing flame retardants are widely used organic flame retardants. When a fire occurs, halogen containing flame retardants will release a large amount of smoke and toxic hydrogen halide gas, causing secondary hazards. With the issuance of the EU RoHs and WEEE directives, the application of organic halogenated flame retardants in fields such as electronic and electrical equipment has been greatly restricted. In the research and development of flame retardant materials, methyl triphenylphosphine bromide cas:1779-49-3 can be used as one of the raw materials for flame retardant additives. Through synergistic effects with other flame retardants, the flame retardant performance of the material can be significantly improved. This characteristic makes it widely used in various fields such as architecture, transportation, electronics, and textiles.
