β-Gem 1
Analytical and Semi-Preparative Columns
β-Gem1 is a π-acceptor chiral stationary phase and is prepared by covalently bonding N-3, 5-dinitrobenzoyl-3-amino- 3-phenyl-2-(1,1-dimethylethyl)-propanoate, to 5 µm silica through an ester linkage.
In many cases, this chiral phase considerably outperforms its widely used analog, phenylglycine. It can separate anilide derivatives of chiral carboxylic acids, including nonsteroidal anti-inflammatory agents.
