The Chemical Weapons Convention (CWC) is an international treaty that poses a complete ban on chemical weapons.

To support the verification regime and declaration requirements imposed by the convention, the CWC contains an Annex on Chemicals composed of three schedules: Schedule 1, Schedule 2, and Schedule 3. On November 27, 2019, the 24th Conference of State Parties to the CWC approved the addition of previously unscheduled chemicals to Schedule 1. The amendment will enter into force on June 7, 2020.

Each Schedule is divided into a part A, which lists chemical warfare agents, and a part B, which lists chemical precursors.

Schedule 1 comprises chemicals that are regarded exclusively or almost exclusively as chemical warfare agents or precursors for their synthesis. Conversely, Schedules 2 and 3 comprise dual-use chemicals that have also legitimate, non-military commercial applications, on a smaller scale for Schedule 2, and on a larger scale for Schedule 3.

While some of the entries in the CWC Schedules identify individual chemicals, other identify families of related chemicals, defined as a central chemical scaffold bearing a number of attached variable chemical groups.

It is worth emphasizing that the purpose of the CWC schedules is to support the treaty’s verification regime and declaration requirements. The schedules should not be construed as an exhaustive compilation of chemical warfare agents and precursors. Indeed, the CWC includes in its definition of chemical weapons  “any chemical (emphasis added) which through its chemical action on life processes can cause death, temporary incapacitation or permanent harm to humans or animals.” Hence, any weapon designed to bring about death, temporary incapacitation, or permanent harm through the toxic properties of chemicals is to be considered a chemical weapon, and any toxic chemical at the basis of such weapons is to be considered a chemical warfare agent.

The table below lists all of the entries of the three CWC Schedules, curated and structurally annotated. An “Overlap Analysis” column shows the corresponding entries in the Australia Group (AG) “Chemical Weapons Precursors” list and the Wassenaar Arrangement’s Munitions List 7 (ML7) .

New. This table is presented in a new format, with live links to PubMed cards, 3D structures (through iCn3D), and MolView cards, which provide a good compendium of the available data, including analytical spectra.

A document in which the CWC Schedules are annotated with chemical structures and three-dimensional models has been produced by the Organisation for the Prohibition of Chemical Weapons (OPCW): “The Science for Diplomats” Annex on Chemicals – A user friendly and scientifically annotated version of the Chemical Weapons Convention Annex on Chemicals
