Description
Sarin (GB), a nerve agent, is one of the most toxic of the known chemical warfare agents. Exposure to sarin can cause death in minutes. A fraction of an ounce (1 to 10 mL) of GB on the skin can be fatal. GB is an odorless, colorless, tasteless, nonflammable liquid @ 15 ℃ and 1 atm. GB has no warning properties, especially when pure, and it can take away your sense of smell.Sarin, also known as ''nerve agent Gas B'' or GB, is an organophosphorus compound, a colourless and odourless liquid
Characteristics

56 °C @ Press: 16 Torr
Non-flammable (EPA, 1998)
Hydrolyzed by water, rapidly hydrolyzed by dilute aqueous sodium hydroxide. Water alone removes Fluoride atom producing nontoxic acid [Merck 11th ed. 1989].
