Bis(2-mercaptoethyl) sulfone Chemical Properties,Usage,Production
Chemical Properties
White Crystalline Solid
Uses
Bis(2-mercaptoethyl) sulfone is a useful reagent for the reduction of disulfides in aquous solutions. It is a superior substitute for DTT.
Uses
Reagent for reduction of disulfide bonds in aqueous solutions.
reaction suitability
reagent type: reductant
Purification Methods
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.
