2-Propanethiol Chemical Properties,Uses,Production

Chemical Properties

liquid with an exceedingly unpleasant smell


Standard for petroleum analysis, intermediate.


ChEBI: An alkanethiol that is propane substituted by a sulfanyl group at position 2.

General Description

White liquid with a strong skunk-like odor.

Air & Water Reactions

Highly flammable. Soluble in water.

Reactivity Profile

2-Propanethiol is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. May liberate hydrogen sulfide when mixed with an acid.


Highly flammable, dangerous fire hazard.

Health Hazard

Inhalation causes loss of sense of smell, muscular weakness, convulsions, respiratory paralysis. Ingestion causes nausea and vomiting. Contact with eyes or skin causes irritation.

Fire Hazard

Flash Point (°F): -30 ℃; Flammable Limits in Air (%): No data; Fire Extinguishing Agents: Dry chemical, alcohol foam, or carbon dioxide; Fire Extinguishing Agents Not To Be Used: Water may be ineffective; Special Hazards of Combustion Products: Irritating sulfur dioxide gas is formed in fires; Behavior in Fire: Vapor is heavier than air and may travel to a source of ignition and flash back. Containers may explode; Ignition Temperature: No data; Electrical Hazard:No data; Burning Rate: No data.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Purification Methods

Purify it as for propane-1-thiol above. [Beilstein 1 IV 1498.]
