Product Details
Our Ethyltriphenylphosphonium bromide product typically comes as a high-purity white or off-white crystalline powder. It dissolves well in common organic solvents like ethanol, chloroform, and dichloromethane, and has some solubility in water as well. It is widely used as an effective dyeing reagent. Similar to other phosphorus-based salts, it also exhibits promising antiviral activity, broadening its potential uses.

Product Usage
Ethyltriphenylphosphonium Bromide (ETPB) is a versatile phase-transfer catalyst with outstanding performance. It significantly speeds up the curing process of phenolic epoxy resins, selected fluoroelastomer resins and thermosetting powder coatings, greatly improving production efficiency. It also works as a reliable catalyst for various organic synthesis reactions, and acts as a high-purity pharmaceutical intermediate for the pharmaceutical industry.
ETPB serves as a key reactant in multiple high-value synthetic pathways: it supports the production of D-amino acids from L-cysteine-based thiazolidines, the synthesis of Leiodolide A through aldol reactions, and the smooth progress of Horner–Wadsworth–Emmons olefination.
In addition, it is used to prepare cycloalkanoindolines via diastereoselective intramolecular imino-ene reactions. It also acts as a dedicated reagent in solid-state metathesis polycondensation to manufacture alkyl-dipropenylthiophene monomers, and is widely adopted in Mizoroki–Heck cyclization and cascading Tsuji–Trost cyclization reactions.
