new derivatization strategy for the detection and identification of sulfur mustard (HD) via liquid chromatography–electrospray ionization–tandem mass spectrometry (LC‐ESI‐MS/MS) is developed. The method incorporates selective oxidation of the sulfide group by the electrophilic iodine reagent N‐iodosuccinimide (NIS) to produce sulfur mustard monoxide (HDSO). The derivatization reaction efficiencies were
提出了一种通过液相色谱-电喷雾电离-串联质谱(LC-ESI-MS / MS)检测和鉴定硫芥菜(HD)的新衍生化策略。该方法结合了亲电子碘试剂N-碘代琥珀酰亚胺(NIS)对硫化物基团的选择性氧化,从而生成一氧化硫芥子油(HDSO)。用加标浓度为50-5000 pg / ml的HD的土壤,沥青,布料,Formica和油毡的乙腈提取物评估了衍生化反应的效率,发现与纯乙腈相似。当前的衍生化方法是第一个保留氯基团身份并支持HD调节和证据发现的方法。
