13C4-secobarbital as the internal standard for the quantitative determination of secobarbital--a critical evaluation


In this study, 13C4-secobarbital was used as an exemplar compound to illustrate the mechanism based on which the effectiveness of a proposed internal standard (IS) could be evaluated. A deuterated analog, 2H5-secobarbital, was also studied in parallel for comparison purposes. Well-established solid-phase extraction and methylation procedures were used prior… (More)
