General description

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

N-Nitrosodiethylamine belongs to the group of toxic nitrosamines, known to show carcinogenic, mutagenic, and hepatotoxic properties. It is formed as a byproduct during food processing, pharmaceutical processing, and water treatment. As a result, they are generally found in water, fish, meat, drug substances, etc.

Application

The CRM can be used as follows:
  • Simultaneous analysis of N-nitrosodiethanolamine, N-nitrosodiethylamine, triethanolamine, diethanolamine in cosmetic samples using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS)
  • Solid phase extraction of N-nitrosodimethylamine and N-nitrosomethylethylamine from eight sartans, ranitidine, and metformin and also the fortified products of these drugs, for quantification by gas chromatography-tandem mass spectrometry (GC-MS/MS)
  • Multi-residue analysis of seven restricted nitrosamines in two body creams and two shower gel samples by vortex-assisted reversed-phase dispersive liquid-liquid microextraction (VA-RP-DLLME) and liquid chromatography-mass spectrometry (LC-MS)
  • Quantitative analysis of four nitrosamines in four sartan drug substances— candesartan cilexetil, olmesartan medoxomi, irbesartan, and valsartan, by gas chromatography-tandem mass spectrometry (GC-MS/MS)
  • Determination of eight volatile nitrosamines in 28 popular meat product samples using ultrasonic solvent extraction combined with solid phase microextraction (SPME) and GC-MS

N-Nitrosodiethylamine (NDEA) is DNA reactive after bioactivation and produces tumors in every animal species tested. Bioactivation is effected by several P450 isozymes including CYP2E1, which is ethanol inducible. Tumor formation in rat liver was proportional to O4-ethyldeoxythymidine formation in DNA
