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.

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.

The Table below shows lists all of the entries of the three CWC Schedules, annotated with chemical structures and with a reference to the corresponding entry in the Australia Group (AG) “Chemical Weapons Precursors” list and the Wassenaar Arrangement’s Munitions List 7 (ML7) . For entries that identify individual chemicals, the Chemical Abstract Service (CAS) registry number is given as well.

This site is under construction! The table will be updated soon to include structures for each entry, SMILE identifiers, as well as downloadable 2D structures in SDF and MRV format.
