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.
In organic chemistry, a sulfide (British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. [ 1 ]

Some metal sulfides, when exposed to a strong mineral acid, including gastric acids, will release toxic hydrogen sulfide. Organic sulfides are highly flammable. When a sulfide burns it produces sulfur dioxide (SO 2) gas. Hydrogen sulfide, some of its salts, and almost all organic sulfides have a strong and putrid stench; rotting biomass ...
Thiophenol is an organosulfur compound with the formula C 6 H 5 SH, sometimes abbreviated as PhSH. This foul-smelling colorless liquid is the simplest aromatic thiol.The chemical structures of thiophenol and its derivatives are analogous to phenols, where the oxygen atom in the hydroxyl group (-OH) bonded to the aromatic ring in phenol is replaced by a sulfur atom.

3,4-Toluenedithiol is an organosulfur compound with the formula CH 3 C 6 H 3 (SH) 2.It is encountered as a colorless wax or oil. The compound is classified as an aromatic dithiol.
Humans and other animals have an exquisitely sensitive sense of smell toward the odor of low-valent organosulfur compounds such as thiols, sulfides, and disulfides. Malodorous volatile thiols are protein-degradation products found in putrid food, so sensitive identification of these compounds is crucial to avoiding intoxication.
