Propanethiol is an organic compound with the molecular formula C₃H₈S. It belongs to the group of thiols. It is a colorless liquid with a strong, offensive odor. It is moderately toxic and is less dense than water and slightly soluble in water. It is used as a feedstock for insecticides.[http://www.chemicalbook.com/ChemicalProductProperty_EN_CB6852694.htm 1-Propanethiol] {{Webarchive|url=https://web.archive.org/web/20150620091405/http://www.chemicalbook.com/ChemicalProductProperty_EN_CB6852694.htm |date=2015-06-20 }}, chemicalbook.com It is highly flammable and it gives off irritating or toxic fumes (or gases) in a fire. Heating it will cause rise in pressure with risk of bursting.[http://www.inchem.org/documents/icsc/icsc/eics1492.htm 1-Propanethiol], inchem.org[https://www.cdc.gov/niosh/ipcsneng/neng1492.html 1-Propanethiol], International Chemical Safety Card
