|Section2= |Section3= }} Tris(2-chloroethyl)amine is the organic compound with the formula N(CH2CH2Cl)3. Often abbreviated HN3, it is a powerful blister agent and a nitrogen mustard gas (although it is not a gas) used for chemical warfare. HN3 was the last of the nitrogen mustard agents developed. It was designed as a military agent and is the only one of the nitrogen mustards that is still used for military purposes. It is the principal representative of the nitrogen mustards because its vesicant properties are almost equal to those of HD and thus the analogy between the two types of mustard is the strongest.〔(NITROGEN MUSTARD HN-3 ). Emergency Response Safety and Health Database. National Institute for Occupational Safety and Health. August 22, 2008. Accessed April 10, 2009.〕 As a vesicant the use and production is strongly restricted within the Chemical Weapons Convention where it is classified as a Schedule 1 substance. ==Mode of action== Nitrogen mustards react via an initial cyclization to the corresponding quaternary aziridine salt. The rate of this reaction is pH dependent because the protonated amine cannot cyclize. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HN3 (nitrogen mustard)」の詳細全文を読む スポンサード リンク
