(1-Propyl)triphenylphosphonium bromide is an organic chemical compound. It is a colorless solid that is soluble in organic solvents such as chloroform and ether, but insoluble in water. The chemical structure of (1-propyl)triphenylphosphonium bromide was determined by NMR spectra and chemical ionization mass spectroscopy. The viscosity of the liquid at room temperature is 0.5 Pa·s. Reaction intermediates have been detected by GC/MS analysis, which includes protonated 1-propyl triphenylphosphonium cation, phosphonium ylide, and phosphonium carbenoid. This product has shown inhibitory effects on the reaction between aldehyde groups and fatty acid chains in the presence of potassium hydroxide or sodium hydroxide solutions.
