Bis(2-mercaptoethyl) sulfone 化学特性,用途語,生産方法
化学的特性
White Crystalline Solid
使用
Bis(2-mercaptoethyl) sulfone is a useful reagent for the reduction of disulfides in aquous solutions. It is a superior substitute for DTT.
純化方法
BMS recrystallises from hexane as white fluffy crystals. Large amounts are best recrystallised from de-oxygenated H2O (charcoal). It is a good alternative reducing agent to dithiothreitol. Its IR (film) has 2995, 2657, 1306, 1248, 1124 and 729 cm-1 . The synthetic intermediate thioacetate has m 82-83o (white crystals from CCl4). The disulfide is purified by flash chromatography on SiO2 and elution with 50% EtOAc/hexane and recrystallised from hexane, and has m 137-139o.
