N-亚硝基二甲胺

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. It is analyzed using GMP validated instruments as per pharmacopeia monograph methods and is traceable to Unites States Pharmacopeia (USP), European Pharmacopeia (EP), and British Pharmacopeia (BP) primary standards, wherever applicable.

It is provided with a comprehensive certificate of analysis (CoA) containing a certified purity value, calculated by the mass balance approach. All information regarding the use of this CRM can be found on the certificate of analysis.N-Nitrosodimethylamine (NDMA) is a nitrosamine that occurs as an impurity in sartan angiotensin II receptor blocker drugs.

N-Nitrosodimethylamine CRM may also find uses as given below:

• Determination of N-Nitrosodimethylamine (NDMA) as an impurity in four valsartan APIs and tablets by high-performance liquid chromatography (HPLC)
• Quantitative analysis of NDMA in valsartan pharmaceutical formulations by capillary electrophoresis-nanospray-mass spectrometry
• Simultaneous determination of N-nitrosodimethylamine and N-nitrosomethylethylamine in drug substances and products containing sartans, ranitidine, and metformin by solid-phase extraction (SPE) and gas chromatography-tandem mass spectrometry (GC-MS/MS)
• Analysis of NDMA in the olmesartan API and tablets by high-performance liquid chromatography-mass spectrometry (HPLC-MS)
• Development and validation of an HPLC-MS/MS method for separation and quantification of NDMA impurity for quality control of ranitidine products
