Application

γ-DEX™ 225 GC column was used during asymmetric highly enantioselective copper catalytic conjugate addition of Et2Zn to enones, using monodentate chiral spiro phosphoramidite ligands.

Chem/Phys Resistance

Temp. Limits: 30 °C to 230 °C

General description

The chiral stationary phase in γ-DEX 225 columns contains 2,3-di-O-acetyl-6-0-TBDMS-γ-cyclodextrin embedded in an intermediate polarity phase.

Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.
