Chemical Reactions of Omeprazole and Omeprazole Analogues. VI. The Reactions of Omeprazole in the Absence of 2-Mercaptoethanol.

Abstract
The reactions of omeprazole, 5-methoxy-2-(4-methoxy-3,5-dimethyl-2-pyridinylmethylsulfinyl)-1H-benzimidazole, and some omeprazole analogues in acidic solution in the absence of 2-mercaptoethanol have been studied. The very complex spectrum of reactions also include the reactions of various degradation products of omeprazole.
