DescriptionECHEMI Editorial Referencecolourless liquid with a penetrating, Ethyl mercaptan is a yellowish liquid (or a colorless gas above the BP). Strong, sharp odor of garlic or skunklike odor. Colorless to yellow liquid; fruity, sulfur aroma.
Ethyl mercaptan appears as a clear colorless low-boiling liquid (boiling point 97°F) with an overpowering, garlic-like/skunk-like odor. Flash point -55°F. Less dense than water and very slightly soluble in water. Vapors are heavier than air. Vapors may irritate nose and throat. May be toxic if swallowed, by inhalation or by contact. Added to natural gas as an odorant. Used as a stabilizer for adhesives.|Liquid|COLOURLESS LIQUID WITH PUNGENT ODOUR.|Colourless to yellow liquid; Fruity, sulfur aroma|Colorless liquid with a strong, skunk-like odor.|Colorless liquid with a strong, skunk-like odor.

Ethyl mercaptan appears as a clear colorless low-boiling liquid (boiling point 97°F) with an overpowering, garlic-like/skunk-like odor. Flash point -55°F. Less dense than water and very slightly soluble in water. Vapors are heavier than air. Vapors may irritate nose and throat. May be toxic if swallowed, by inhalation or by contact. Added to natural gas as an odorant. Used as a stabilizer for adhesives.|Ethanethiol is an alkanethiol that is ethane substituted by a thiol group at position 1. It is added to odorless gaseous products such as liquefied petroleum gas (LPG) to provide a garlic scent which helps warn of gas leaks. It has a role as a rodenticide.
Moderately toxic by ingestion, inhalation, and intraperitoneal routes. A skin and eye irritant. Inhalation causes central nervous system effects in humans. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. A moderate explosion hazard when exposed to spark or flame. Violent reaction with Ca(OCl)2. Will react with water or steam to produce toxic and flammable vapors. To fight fire, use CO2, dry chemical. When heated to decomposition or on contact with acid or acid fumes it emits hghly toxic fumes of SOx. See also MERCAPTANS.
This material is used as a warning odorant for liquefied petroleum gases. It is used as an intermediate in the manufacture of many pesticides and other organic chemicalsBasic Info-
