| 25 | Chromatographically the sulfoxide is more polar than the parent and elutes earlier on [[Reverse-phase HPLC|reverse phase]], usually with adequate resolution. It therefore appears as a distinct related substance on a competent method and is included in an itemised related-substances table; resolving it from the parent is part of what a specificity assessment demonstrates.{{r|ich_q2}} | 25 | Chromatographically the sulfoxide is more polar than the parent and elutes earlier on [[Reverse-phase HPLC|reverse phase]], usually with adequate resolution.
