C20H20BrPCAS 1530-32-1Phase Transfer Catalysts
Ethyl Triphenyl Phosphonium Bromide
Quaternary phosphonium salt used as a Wittig olefination reagent and phase transfer catalyst.
Ethyl triphenyl phosphonium bromide (ETPPB) is an organophosphorus quaternary salt widely used as the precursor to the ethylidene ylide in Wittig reactions, converting aldehydes and ketones into alkenes. It also serves as an effective phase transfer catalyst in organic synthesis and as an accelerator or curing catalyst in epoxy resins and powder coatings. Specification, assay and packaging are confirmed per enquiry.
