Applications:


HPLC Separation of Aminobiphenyls



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.

4-Aminobiphenyl

HPLC Separation of Aminobiphenyl Isomers in Cation-Exchange Mode

chr_308.gif

Two isomers of aminobiphenyl were successfully retained and separated in cation-exchange mode on a Primesep S2 column. Primesep S2 column is a HILIC/cation-exchange column that can be operated in HILIC, cation-exchange, and anion-exclusion modes. Method and column are compatible with ELSD/LC/MS and UV and can be used for routine analysis of polar molecules.



Application Analytes:

2-Aminobiphenyl
4-Aminobiphenyl

Separation of Toluidine and Aminobiphenyl Isomers

Toluidine isomers and aminobyphenyl isomers are organic compounds each with a substituted amine group. Primesep 200 was used to separate these isomers. Primesep 200 separates isomers by interacting with polar molecules, retaining basic compounds, and additionally by reverse phase mechanism.
