EA-2192 is an extremely toxic degradation product of the VX nerve agent.^[1]^[2] It is a white solid that is very soluble and stable in water.

EA-2192 is an extremely potent acetylcholinesterase inhibitor. It is almost as toxic as VX itself.^[3]

EA-2192 behaves similar to aged Soman as it is the dealkylated form of VX and cannot be reversed with common oxime reactivators.
