摘要：

The concentration of dimethyl sulfide (DMS) in seven different samples of research grade dimethyl sulfoxide (DMSO), including one deuterated sample, was measured by GC-MS. The average concentration of DMS is 0.48 +/- 0.14 mM (range: 0.44-0.55 mM) and ca. 0.35 mM in DMSO-d(6). The presence of DMS in DMSO is potentially problematic for compounds that are susceptible to reaction with DMS and are present at mM-mM concentrations. Standard methods of purification of DMSO were unsuccessful in removing all traces of DMS.
