A simple HPLC-UV method for the determination of dimenhydrinate and related substances – identification of an unknown impurity
Abstract:During the revision of the dimenhydrinate monograph of the European Pharmacopoeia a HPLC-UV method was developed. The procedure described allows a qualitative and quantitative determination of both dimenhydrinate compounds and of thirteen related substances. Furthermore a hitherto unknown impurity was identified and integrated into the purity check. Also 18 samples of dimenhydrinate have been tested. Thereby the relevant impurities of dimenhydrinate could be nominated and quantified.
