(1’S,2'S)-Nicotine 1'-Oxide and (1’R,2'S)-Nicotine 1'-Oxide Mixture

Nicotine-1’-N-oxide is a derivative of Nicotine (N412420) found in the leaves, stems, and roots of N. tabacum, N. affinis and N. sylvestris. Nicotine-1’-N-oxide has also been identified as a metabolite of nicotine in animals and in man. The metabolism of nicotine in man proceeds by alternative routes of oxidation of nitrogen to form nicotine-1’-N-oxide (both diastereomers) or cotinine. A representative lot had a 1.0 : 1.6 ratio.
