一般描述
二甲基二硫 (DMDS) 是一种有机二烷基二硫化物。是我国典型城市生活垃圾填埋场工作面发现的有臭味化合物之一。DMDS 与单不饱和醋酸盐通过碳-碳双键加成形成加合物。这些加合物有助于确定长链单不饱和醋酸酯中双键的位置。用密度泛函理论 (DFT) 和高分辨电子能量损失谱 (HREELS) 研究了 DMDS 在 Au (111) 表面的吸附。
应用
二甲基二硫 (DMDS) 可用于烯烃的衍生化，以 MS 法测定双键的位置。也可用于结合 GC-MS 分析确定 嗜冷弯曲杆菌 中单不饱和脂肪酸的双键位置。

Location of the double-bond position of monounsaturated fatty acids in Campylobacter cryaerophila was accomplished with combined gas chromatography-mass spectrometry analysis of dimethyl disulfide (DMDS) derivatives. The monoenoic fatty acids from whole bacterial cells were converted to methyl esters and then
