Other Notes

Chiral diamine with hindered inversion at the nitrogen atoms

Packaging

100 mg in glass bottle

Bottomless glass bottle. Contents are inside inserted fused cone.

Application

It was used as an standard analyte for testing the enantioseparation capability of the chiral stationary phase column; in a study to understand the covalently bonded cellulose tris(3,5-dimethylphenylcarbamate) on a silica monolithic capillary column.

General description

Tröger base (TB) is a chiral heterocyclic amine with chirality due to the presence of two stereogenic nitrogen atoms.
