This certified Snap-N-Spike® solution is suitable for use as an internal standard for quantification of NNAL levels in urine or other matrices for nicotine testing by LC-MS/MS or GC/MS. NNAL is a metabolite of NNK or 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone. Measurement of NNAL levels in urine is a reliable way to determine NNK exposure in smokers, non-smokers exposed to environmental tobacco smoke (ETS), or users of smokeless tobacco products such as chewing tobacco or snuff.

100 µg/mL in Methanol
Also known as nicotine-derived nitrosamine ketone, NNK is a potent carcinogen and biomarker of exposure to cigarette smoke. NNK, produced upon the curing of tobacco, is found in a variety of tobacco products including chewing tobacco, snuff, cigarettes, and cigars. This stable-labeled internal standard is suitable for use in LC-MS/MS or GC/MS applications in nicotine testing, environmental monitoring, or clinical and diagnostic testing of nicotine biomarkers.
