D-Trp(23)-Teriparatid ist eine sequenzvariante Peptidverunreinigung von Teriparatid, bei der der terminale L-Tryptophan-Rest durch das D-Enantiomer ersetzt ist, wodurch ein stereochemisches Analog und kein Verkürzungsprodukt entsteht. Solche epimeren Verunreinigungen können durch Racemisierung während der Festphasensynthese, bei Deprotektionsschritten oder unter Lagerungsstress entstehen. Da Summenformel und Molekulargewicht nicht angegeben sind, beruht die Strukturzuordnung auf orthogonaler Charakterisierung. Die empfindliche Bestimmung erfordert in der Regel LC-MS/MS mit chiraler oder hochauflösender Trennung, ergänzt durch Peptid-Mapping und gegebenenfalls Ionenmobilität oder NMR zur Bestätigung der Konfigurationsinversion.
