N-Nitrosoanabasine or NAB is a potent carcinogen and biomarker of exposure to cigarette smoke. It′s found in a variety of tobacco products including chewing tobacco and snuff. Certified Spiking Solutions® are suitable for use in LC-MS/MS or GC/MS methods for nicotine testing, environmental monitoring, or clinical and diagnostic testing of nicotine biomarkers.

Tobacco-specific nitrosamines (TSNA) are among the most important and abundant strongly carcinogenic agents in unburned tobacco. It has been established that 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) induces lung tumors in rodents independent of the route of administration. N'-Nitrosonornicotine (NNN) causes tumors of the
Exposure to tobacco-specific nitrosamines (TSNA) has been measured in the saliva of 12 users of Sudanese oral snuff (toombak). Using GC coupled to thermal energy analysis, levels of N'-nitrosonornicotine (NNN), N'-nitrosoanatabine (NAT), N'-nitrosoanabasine (NAB) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) were measured before
We compared the metabolism in the F-344 rat of the moderately potent esophageal carcinogen N'-nitrosonornicotine (NNN, 2'-(3-pyridyl)-N-nitrosopyrrolidine) and its weakly active homologue N'-nitrosoanabasine (NAB, 2'-(3-pyridyl)-N-nitrosopiperidine). Urine was the major pathway of excretion for both nitrosamines. The major urinary metabolites of

In many countries nicotine-containing chewing gum (Nicorette) is used to help to break the habit of smoking. Saliva was collected every 5 min from chewers of nicotine chewing gum and analysed for tobacco-specific nitrosamines. Detectable levels of tobacco-specific nitrosamines were
