Tetra-n-heptylammonium bromide is used as a mobile phase for the separation of a series of glucosinolates by reversed-phase ion-pair liquid chromatography. It acts as an ion pair reagent, which is used in the extraction of molybdenum complexes into toluene film. Further, it is used in organic synthesis. It is also used in coatings, printing ink, rubber, glass, leather and cosmetics.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
