4-(N-ニトロソメチルアミノ)-1-(3-ピリジニル)-1-ブタノン 化学特性,用途語,生産方法

• 化学的特性

  Off-White Crystals

• 使用

  This compound was present in the highest concentrations in smokeless tobacco out of the nitrosamines identified. Readily produces cancer in rats and hamsters

• 調製方法

  NNK is not produced commercially. NNK is formed by oxidation and nitrosation of nicotine and is produced during the curing, aging, processing, and smoking of tobacco. NNK has been found in tobacco at levels up to 35 mg/kg, in snuff up to 8.3 mg/kg, and in cigarette smoke up to 0.5 mg per cigarette (179, 193). Common cigarette filters considerably reduce the amount of NNK that reaches the smoker. NNK is extracted from snuff by the saliva of users, and as much as 0.2 μg/g of saliva has been measured. Potential exposure to NNK is widespread also among those exposed to sidestream smoke and has been detected at 0.2–15.7 μg/ cigarette. Evidence from one comparative study of tobacco-specific nitrosamines in cigarettes suggests that levels of NNK (measured as a sum of all tobacco-specific nitrosamines) are higher in non-Moldovan cigarette tobacco and Moldovan blended cigarettes, suggesting that current tobacco production and manufacturing technologies may create conditions that favor N-nitrosation of alkaloids and other tobacco constituents.

• 一般的な説明

  Pale yellow crystalline solid.

• 空気と水の反応

  4-(N-NITROSOMETHYLAMINO)-1-(3-PYRIDYL)-1-BUTANONE may be sensitive to prolonged exposure to air and light.

• 反応プロフィール

  A nitrated amine and ketone. 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. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.

• 火災危険

  Flash point data for 4-(N-NITROSOMETHYLAMINO)-1-(3-PYRIDYL)-1-BUTANONE are not available; however, 4-(N-NITROSOMETHYLAMINO)-1-(3-PYRIDYL)-1-BUTANONE is probably combustible.

• 安全性プロファイル

  Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. An experimental teratogen. Mutation data reported. A flammable liquid. When heated to decomposition it emits toxic fumes of NOx.

• 発がん性

  4-(N-Nitrosomethylamino)-1-(3-pyridyl)-1-butanone (NNK) is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
