Separation of Toluidine and Aminobiphenyl Isomers

July 6, 2015

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.

Condition

Column Primesep 200, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer AmFm Ph 3.5
Flow Rate 1.0 ml/min
Detection UV, 250 nm

 

Description

Class of Compounds

Isomers of toluidine 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.

HPLC Method for Separation of Toluidine Isomers on Primesep 200 Coulmn

December 31, 2005

Toluidine isomers are based on toluene and differ whether the primary amine is ortho, meta or para to the methyl group. A Primesep 200 column with an ammonium formate buffer or a Primesep 100 column with sodium phosphate baseline resolves the three regioisomers. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN), ammonium formate, or sodium phosphate and ultraviolet (UV) detection at 250 nm.

Application Column

Column Diameter: 4.6 mm
Column Length: 150 mm
Particle Size: 5 µm
Pore Size: 100 A
