Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell.The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass.
Dimethyl sulfide has a characteristic odor commonly described as cabbage-like.It becomes highly disagreeable at even quite low concentrations. Some reports claim that DMS has a low olfactory threshold that varies from 0.02 to 0.1 ppm [clarification needed] between different persons, but it has been suggested that the odor attributed to dimethyl sulfide may in fact be due to disulfides ...

A sulfide is similar to an ether except that it contains a sulfur atom in place of the oxygen. The grouping of oxygen and sulfur in the periodic table suggests that the chemical properties of ethers and sulfides are somewhat similar, though the extent to which this is true in practice varies depending on the application.
Generic structure of an organosulfate, where R is an organyl group. In organosulfur chemistry, organosulfates are a class of organic compounds sharing a common functional group with the structure R−O−SO − 3.
The major volatile compounds responsible for garlic breath are allyl methyl sulfide, allyl methyl disulfide, allyl mercaptan, diallyl disulfide, dimethyl disulfide and methyl mercaptan, along with minor amounts of dimethyl selenide. [1] [2] [3] Various other sulfur compounds are also produced when allicin in garlic is broken down in the stomach ...
MTT, a yellow tetrazole, is reduced to purple formazan in living cells. [8] A solubilization solution (usually either dimethyl sulfoxide, an acidified ethanol solution, or a solution of the detergent sodium dodecyl sulfate in diluted hydrochloric acid) is added to dissolve the insoluble purple formazan product into a colored solution.
