Thiol
Thiol
Thiol (/ˈθaɪɒl/), also known as mercaptan (/mɜːrˈkæptæn/), is an organic compound that contains a sulfur-hydrogen (S-H) functional group. The term "thiol" is derived from the Greek word "theion" meaning sulfur, with the suffix "-ol" denoting its alcohol-like nature.
Etymology
The term "thiol" was coined in the mid-19th century, derived from the Greek word "theion" for sulfur, combined with the chemical suffix "-ol" indicating its similarity to alcohols. The alternative name "mercaptan" is derived from the Latin "mercaptus" which means "captured" or "seized", referring to the strong binding nature of these compounds.
Properties
Thiols are known for their strong and often unpleasant odors. They are used in the production of many industrial chemicals and are also found in various natural substances, such as garlic and onions. Thiols are similar to alcohols in structure, but the presence of sulfur instead of oxygen results in unique chemical properties.
