 N'-Nitrosonornicotine (CAS NO.16543-55-8) is also called 1'-Demethyl-1'-nitrosonicotine ; 1'-Desmethyl-1'-nitrosonicotine ; 1'-Nitroso-1'-demethylnicotine ; 1'-Nitrosonornicotine ; 1-Nitroso-2-(3-pyridyl)pyrrolidine ; 3-(1-Nitroso-2-pyrrolidinyl)pyridine ; CCRIS 1218 ; HSDB 5114 ; N-Nitrosonornicotine ; NNN ; Nicotine, 1'-demethyl-1'-nitroso- ; Nicotine, 1'-nitroso-1'-demethyl- ; Nitrosonornicotine ; Pyridine, 3-(1-nitroso-2-pyrrolidinyl)-, (S)- . N'-Nitrosonornicotine (CAS NO.16543-55-8) is white crystalline flakes or yellow oil that solidifies on standing in the cold. It is stable, but air and light sensitive. It is incompatible with oxidizing agents. A nitrated amine, nicotine derivative. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. When heated to decomposition it may emit toxic and hazardous fumes of NOx and COx. Flash point data for N'-Nitrosonornicotine (CAS NO.16543-55-8) are not available; however, N'-Nitrosonornicotine (CAS NO.16543-55-8) is probably combustible.
