Know what's VX, the chemical used to kill Kim Jong Nam | Video A screenshot from a CCTV footage, showing Kim Jong Nam at Kuala Lumpur Airport.

Kuala Lumpur: VX, the chemical used in the airport murder of Kim Jong Nam, is one of the deadliest chemical weapons created by mankind. Just 10 mg of the nerve agent or a single drop is enough to kill in minutes, experts say.

What's VX?

» Its full chemical name is S-2 Diisoprophylaminoethyl methylphosphonothiolate.

» It severely disrupts the body's nervous system and is used as a nerve agent in chemical warfare.

» With the texture and feel of engine oil, VX was first produced in the United Kingdom in the 1950s.

» Its only known use is as a chemical warfare agent.

» VX is classified as a weapon of mass destruction by the United Nations.

» Roughly 1/100th of a gram - one third of a drop - on someone’s skin, will kill them, says Bruce Bennet, defense researcher at California-based RAND Corporation.

» VX is considered to be much more toxic by entry through the skin and toxic by inhalation.

» Any visible VX liquid contact on the skin, unless washed off immediately, is believed to be lethal.

» The person may not even know he has been exposed to VX as it is tasteless and odourless.

» Symptoms after contact with VX in vapour form will appear within a few seconds, and within a few minutes to up to 18 hours after exposure to the liquid form.

» It can cause convulsions, loss of consciousness, paralysis and respiratory failure in minutes.

» VX is known to be much more potent than other nerve agent because of its persistency.

» Unlike other chemical weapons, the VX doesn't evaporates from the skin surface.

» It is unlikely to be detected by airport security or sensors if it had been brought in small amounts.

» Sarin gas was used in Syria, killing hundreds in deadly attacks in 2013.

» Sarin gas was also used by members of a Japanese doomsday cult in their deadly 1995 attack on a Tokyo subway.
