N'-Nitrosonornicotine-d4

N'-Nitrosonornicotine-d4 is intended for use as an internal standard for the quantification of N'-nitrosonornicotine (Cay-34120) by GC- or LC-MS. N'-Nitrosonornicotine is a tobacco-specific N-nitrosamine and carcinogen that has been found in unburned tobacco and cigarette smoke. It induces the formation of DNA adducts in isolated rat nasal mucosa and esophagus. N'-Nitrosonornicotine induces tumor formation in rat esophagus and nasal cavity, mouse lung, forestomach, and trachea, and hamster trachea and forebrain. Urinary levels of N'-nitrosonornicotine are positively correlated with the risk of esophageal cancer in smokers.Formal Name: 5-(1-nitroso-2-pyrrolidinyl)-pyridine-2,3,4,6-d4. CAS Number: 66148-19-4.
