Determinazione dell'azoto nei peptidi attivi farmaceutici

La determinazione dell'azoto e delle proteine totali nei prodotti farmaceutici è descritta nei capitoli della Farmacopea Europea (Ph.Eur.) 2.5.9 e 2.5.33, metodo 7 [1, 2]. Nella farmacopea degli Stati Uniti (USP), la determinazione dell'azoto è descritta nel capitolo 461 [3]. Qui vengono specificate diverse tecniche di titolazione. La Ph.Eur. utilizza la retro-titolazione ed utilizza il rosso metile come indicatore, mentre l'USP utilizza la titolazione diretta potenziometrica, con l'utilizzo dell'acido borico.
