General description

Dimethyl trisulfide, belonging to the class of sulfur compounds, is a volatile aroma compound, reportedly identified in Parmigiano Reggiano cheese, roasted sesame seed oil, alcoholic beverages, Brussels sprout, cabbage, cauliflower, commercial rice cakes, etc. It is also reported to be identified as a potential marker for poultry spoilage.

Application

Dimethyl trisulfide may be used as an analytical reference standard
for the quantification of the analyte in the following:
  • Parmigiano Reggiano cheese using ion-exchange chromatography and gas chromatography coupled to mass spectrometry (GC-MS).
  • Rabbit blood samples using gas chromatography coupled to mass spectrometry (GC-MS).

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Some advanced cancer patients suffer from pungent sulfury malodor. To determine the chemical identity of the odorant, we performed gas chromatography-mass spectrometry-olfactometry analysis of volatiles from fungating cancer wounds. We identified the source of the characteristic smell as dimethyl trisulfide
