一般說明
二甲基亚砜是一种有机硫化合物，常用作极性溶剂，能溶解广泛的极性和非极性化合物。它还可用作几种熟知反应的反应试剂，包括Swern氧化、2a Pfitzner-Moffatt氧化和2b Corey-Chaykovsky反应。
應用
二甲基亚砜（DMSO）已用于：
- 制备乙基4-[18F]氟苯甲酸酯。
- 作为3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四氮唑溴化物（MTT）试验的培养基。
- 作为化学合成中的溶剂。
- 溶解和制备小分子、药物和化学化合物的储备溶液，以用于各种检测和实验。
注意
在室温下容易过冷并缓慢重融。 固化产品可以通过加热至室温来重新液化，而不会损害产品。
