Valsartan EP-Impurity C, auch als Valsartan Related Compound B oder Valsartan N-Butyryl Analog bezeichnet, ist eine strukturell definierte synthetische Prozessverunreinigung des Angiotensin-II-Rezeptorantagonisten Valsartan. CAS 952652-79-8; Summenformel C23H27N5O3; Molekulargewicht 421,49 g/mol. Die Verunreinigung unterscheidet sich vom Ausgangswirkstoff durch eine N-Acyl-Homologisierung der valinabgeleiteten Aminofunktion und entspricht damit einem Nebenprodukt, das während Acylierungs- oder Amidierungsstufen der Wirkstoffsynthese entstehen kann. Es handelt sich nicht um ein Nitrosamin, wird jedoch im Rahmen der Verunreinigungscharakterisierung und Spezifikationskontrolle bewertet. Für die Bestimmung werden typischerweise LC-MS/MS, LC-UV und zur Strukturabsicherung LC-HRMS eingesetzt.
