Description
N-Nitroso Metronidazole EP Impurity B is an N-nitroso derivative of the secondary amine present in Metronidazole | which is a highly characterized reference material that meets stringent regulatory standards set for nitrosamine compounds | including those set by USP | EMA | JP | and BP. This nitroso standard is essential for a variety of applications | such as analytical method development | method validation (AMV) | and Quality Control (QC) | particularly in the context of Metronidazole production. It is suitable for use in both Abbreviated New Drug Applications (ANDA) and New Drug Applications (NDA). This nitrosamine standard helps establish detection limits | quantify impurity levels | and ensure trace nitroso impurities in pharmaceutical products remain within FDA and EMA safety limits.
