Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH 2 CH 2 Cl) 2, as well as other species. In the wider sense, compounds with the substituents −SCH 2 CH 2 X or −N(CH 2 CH 2 X) 2 are known as sulfur mustards or nitrogen mustards ...
Sulfur dioxide is an intermediate in the production of sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. The method of converting sulfur dioxide to sulfuric acid is called the contact process. Several million tons are ...
Thiol with a blue highlighted sulfhydryl group.. In organic chemistry, a thiol (/ ˈ θ aɪ ɒ l /; [1] from Ancient Greek θεῖον (theion) 'sulfur' [2]), or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent.

Sulfur mustard, a potent vesicant, was used in World War I as a disabling agent. [12] Sulfur ...
Fresh garlic has little odor until it is chopped or crushed. Allicin is produced from alliin (a derivative of the amino acid cysteine) by the enzyme alliinase. [4] Allicin is unstable and breaks down to form other sulfur compounds such as diallyl sulfides. [5] These compounds contribute to the smell of fresh garlic.
Mercaptan is a harmless chemical that smells like sulfur or rotten eggs that utility companies add to natural gas to make it easier to detect leaks, according to Healthline, a medical information ...
Butane-1-thiol, also known as butyl mercaptan, is a volatile, clear to yellowish liquid with a fetid (extremely foul-smelling) odor, commonly described as "skunk" odor.In fact, 1-butanethiol is structurally similar to several major constituents of a skunk's defensive spray but is not actually present in the spray.
