Ethanethiol/Ethyl mercaptan is an organic compound with the chemical formula C2H6S. It is a colorless and transparent liquid, slightly soluble in water, and easily soluble in alkali, ethanol, ether, and other organic solvents. It is known for its strong, persistent, and irritating garlic odor, and is listed alongside butyl selenethiol as the most odorous substance in the Guinness World Records. When the air contains only 50 billionth of ethyl mercaptan (0.00019mg/L), its odor can be smelled. It is usually used as an odor indicator by adding gas or other substances. When inhaled in large quantities, it can cause difficulty breathing, lower blood pressure, and symptoms such as vomiting and throat discomfort.
