CYCLOBOND I 2000 DMP

β-cyclodextrin, 3,5-dimethylphenyl carbamate

The reaction of the 3,5-dimethylphenyl isocyanate with some of the hydroxyl groups of beta-cyclodextrin results in a π basic phase similar in character to the naphthylethyl carbamate phases. The selectivity is greater for the Astec® CYCLOBOND I 2000 DMP when the chiral center is part of a ring structure or is on the alpha carbon. This phase has been very useful for derivatized amines, like amphetamine ACQ.

Bonded phase: 3,5-Dimethylphenyl carbamate modified beta-cyclodextrin
Operating pH range: 3 - 7
Particle diameter: 5 or 10 μm
Pore size: 100 Å
