VX is a highly toxic chemical compound classified as a nerve agent. It was developed in the 1950s for use in chemical warfare and is known for its ability to disrupt the normal functioning of the nervous system. VX is odorless and tasteless, making it particularly dangerous, as it can be absorbed through the skin or inhaled. Due to its extreme toxicity, VX is banned under the Chemical Weapons Convention. It is considered one of the most lethal substances ever created, with even a small amount capable of causing death within minutes. Its use is strictly regulated and monitored by international organizations.
