Thiol - Wikipedia
WEBIn organic chemistry, a thiol (/ ˈ θ aɪ ɒ l /; from Ancient Greek θεῖον (theion) 'sulfur'), or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group.
Thiols and Sulfides - Chemistry LibreTexts
WEBA thiol is a compound which contains an SH functional group. The -SH group itself is called a mercapto group. A disulfide is a compound containing an -S-S- linkage. (Organic) sulfides have the structure R-S-R′, and are therefore the sulfur analogues of ethers.

6.8: Thiols (Mercaptans) - Chemistry LibreTexts
WEBMay 20, 2021 · Thiols, which are also called mercaptans, are analogous to alcohols. They are named in a similar fashion as alcohols except the suffix -thiol is used in place of -ol. By itself the -SH group is called a mercapto group. The main physical characteristic of thiols is their pungent, disagreeable odor.

Medicinal Thiols: Current Status and New Perspectives - PMC
WEBThiol-containing drugs can reduce radicals and other toxic electrophiles, restore cellular thiol pools, and form stable complexes with heavy metals such as lead, arsenic, and copper. Thus, thiols can treat a variety of conditions by serving as radical scavengers, GSH prodrugs, or metal chelators.
The Thiol Functional Group | ChemTalk
WEBWhat is the Thiol Functional Group? This group consists of a Sulfur atom bonded to both a Hydrogen atom and an R group. The name thiol refers to the fact that it is, essentially, an alcohol group with a Sulfur atom instead of an Oxygen atom. Thiols, like many Sulfur compounds, have an unpleasant odor.
