About this list
Schedule 1 of the Chemical Weapons Convention (CWC), administered by the Organisation for the Prohibition of Chemical Weapons (OPCW), covers chemicals developed, produced or used as chemical weapons that have little or no use for peaceful purposes — including nerve agents (sarin, soman, VX), sulfur and nitrogen mustards, and certain toxins. They carry the strictest controls; production is permitted only in very small quantities for research, medical, pharmaceutical or protective purposes.
