title: Proton magnetic resonance spectroscopic determination of bethanechol chloride in tablets.
abstract: A simple and reliable proton magnetic resonance spectroscopic method was developed for the assay of bethanechol chloride in tablets. The proposed method entails a minimum of procedural steps and reagents. The recovery of bethanechol chloride from synthetic formulations was 99.9 +/- 0.4% (n = 15), CV = 0.4%. Mean assay values for 25 and 10 mg commercial tablets were 100.5% (n = 8) and 99.7% (n = 7) of declared, respectively. A detailed interpretation of the proton magnetic resonance spectrum is also presented.
