General description
Tetrapentylammonium bromide is a quaternary ammonium bromide, with pentyl chains and a bromide counter-ion, which is widely used as an ion-pair reagent in analytical applications.
Application
Tetrapentylammonium bromide may be used as a standard, to examine the effects of annealing membranes formed by mixture-casting ”Nafion” mainly based on the selectivity, ion-exchange capacity, and mass transport in the membranes. It may also be used as an ion pair reagent in the analysis of antioxidant phenolic compounds in wines, juices using two-dimensional liquid chromatography and sulfonated lignins in agrochemical formulations using one-, two-dimensional liquid chromatography techniques.
Other Notes
用于离子对色谱的添加剂；比四丁基同系物增加了保留时间
