Description of Ethanethiol
Ethanethiol, commonly known as ethyl mercaptan, is a colorless gas or clear liquid with a distinct odor. It is an organosulfur compound with the formula CH3CH2SH. Abbreviated EtSH, it consists of an ethyl group (Et), CH3CH2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with S instead of O. The odor of EtSH is infamous. Ethanethiol is more volatile than ethanol due to a diminished ability to engage in hydrogen bonding. Ethanethiol is toxic. It occurs naturally as a minor component of petroleum, and may be added to otherwise odorless gaseous products such as liquefied petroleum gas (LPG) to help warn of gas leaks. At these concentrations, ethanethiol is not harmful.

What is C2H5SH?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Ethanethiol which has developed particularly rapidly in recent years. Do you know about Ethanethiol?
- The official answer: Ethanethiol is a common thiol with the chemical formula C2H6S, structurally obtained by replacing the oxygen atom in ethanol with sulfur. It is a colourless, transparent and volatile highly toxic oily liquid, slightly soluble in water and easily soluble in alkaline and organic solvents, and is known for its strong, persistent and irritating garlic odour. It is the most smelly substance included in the 2000 edition of the Guinness Book of World Records. The air contains only one part in 50 billion of ethanethiol (0.00019mg/L).
What’s the application of C2H5SH?
Ethanethiol is an important pesticide intermediate, used in the production of organophosphorus pesticides isoprophos, methomyl, ethanephos, endosulfan, methyl endosulfan, etc… It can also be used in the production of antimicrobial agent 401. When the air contains ethanethiol at a concentration of only 50 billion parts Chemicalbook, its odour can be detected, so it can be used as a warning agent for natural gas and LPG, and as an odorant for reagents (its odour can be detected at a concentration of 0.00019mg/L). Ethanethiol can also be used in organic synthesis such as pharmaceuticals.
