Compound: 3-Aminobiphenyl

HPLC Separation of Aminobiphenyls

Application Notes:

Aminobiphenyls consist of isomers that differ only in the location of a primary amine group on an aromatic ring. 2-, 3-, and 4-aminobiphenyl are separated on a Primesep D with good peak shape and a short retention time by a mixture of reversed-phase and ion-exclusion interactions. Peak order can be reversed for 2- and 3-aminobiphenyls by using ammonium formate buffer without pH adjustment. The HPLC separations use a mobile phase of water, acetonitrile (MeCN, ACN), ammonium formate buffer or acetic acid (HOAc) with UV detection at 250 nm.

Application Columns:

Primesep^® D is a reversed-phase HPLC column with general hydrophobic and ion-exchange properties for direct injection of plasma samples. The Primesep D stationary phase combines a hydrophobic chain and a basic functional group as an anion exchanger. Primesep D excludes high molecular weight plasma compounds while retaining hydrophobic and acidic small molecules. Methods can be developed on Primesep columns that are fully compatible with detectors such as UV, RI, conductivity, fluorescence, evaporative light scattering (ELSD) as well as mass spectrometers (LC/MS) and preparative chromatography (prep HPLC) systems.
