In naming these compounds, the suffix -thiol is appended to the name of the appropriate hydrocarbon; e.g., CH3CH2CH2CH2SH is named butanethiol. The prefix mercapto- is placed before the name of a compound if the ―SH group is to be named as a substituent, as in …

WebEthanethiol, commonly known as ethyl mercaptan, is an organosulfur compound with the formula CH 3 CH 2 SH. is a colorless liquid with a distinct odor. Abbreviated EtSH, it consists of an ethyl group (Et), CH 3 CH 2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with sulfur in place of oxygen.The odor of EtSH is infamous. In organic chemistry, a thiol , 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 are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl (−OH) group of an alcohol), and the word is a blend of "thio-" with "alcohol".
Web1-Dodecanethiol (DDT) is an alkyl thiol that forms a self-assembled monolayer (SAM) and can be used as an organic source of sulfur with balanced physio-chemical properties. Application DDT can be used as a source of sulfur for the synthesis CdS quantum dots (QDs) and lead sulfide nanoparticles (PbS) which find potential applications in energy efficient …
