"o Isopropylmethyl Phosphonofluoridate," commonly referred to as IMPF, is a highly toxic organophosphorus compound used primarily as a chemical warfare agent. It is also known by its chemical formula, C4H10FO2P, and its systematic name, methyl(isopropoxy)(fluorophosphoryl)ethane.
IMPF is a nerve agent that affects the cholinergic system, which is essential for transmitting nerve impulses. Exposure to this compound can lead to severe health consequences, including respiratory distress, muscular paralysis, convulsions, and ultimately, death due to respiratory failure if not treated promptly.
This highly volatile liquid is colorless, odorless, and has a relatively low boiling point. It is soluble in organic solvents but has limited solubility in water.
Due to its extreme toxicity, the production, possession, and use of IMPF are strictly regulated under international conventions. It is classified as a Schedule 1 substance, meaning it has no legitimate uses outside of authorized research for defense purposes.
IMPF is often considered a chemical weapon due to its potent nerve-gas properties. Its most notorious publicized use was in the 1995 Tokyo subway attack, where it was released in liquid form, causing a significant number of casualties and widespread panic.
Given its dangerous nature, IMPF is of significant concern to global security, and stringent measures are in place to prevent its production, stockpiling, or unauthorized use.
