Abstract:
Compounds of the 4,5-epoxymorphinan series have been shown to degrade in solution to the corresponding 2,2'-dimers when stored in amber glass HPLC vials. A colorant in the glass has been shown to catalyze the degradation. Although amber glass is routinely used to protect solutions from light degradation, it should not be used without evaluating its effect on sample stability.
