Sulfanyl (HS^•), also known as the mercapto radical, hydrosulfide radical, or hydridosulfur, is a simple radical molecule consisting of one hydrogen and one sulfur atom. The radical appears in metabolism in organisms as H₂S is detoxified. Sulfanyl is one of the top three sulfur-containing gasses in gas giants such as Jupiter and is very likely to be found in brown dwarfs and cool stars. It was originally discovered by Margaret N. Lewis and John U. White at the University of California in 1939.^[4] They observed molecular absorption bands around 325 nm belonging to the system designated by ²Σ⁺ ← ²Π_i. They generated the radical by means of a radio frequency discharge in hydrogen sulfide.^[5] HS^• is formed during the degradation of hydrogen sulfide in the atmosphere of the Earth. This may be a deliberate action to destroy odours or a natural phenomenon.^[6]

The organic analogue of sulfanyl is thiyl radical with the formula RS^•, where R is some organic group (e.g., alkyl or aryl).
