The Wassenaar Arrangement is an international framework that was established with the objective of “promoting transparency and greater responsibility in transfers of conventional arms and dual-use goods and technologies.”

Within its Munitions List 7 (ML7), the Wassenaar Arrangement features chemical agents, biological agents, riot control agents, radioactive materials, related equipment, components, and materials.

In particular, with regards to chemical agents, ML7 comprises all of the CWC Schedule 1 chemicals, the central incapacitating agent 3-quinuclidinyl benzilate (BZ), which is a CWC Schedule 2 chemical, as well as a list of defoliants and a list of riot control agents, neither of which is in the CWC schedules.

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

New. The table is now downloadable in SDF, CSV, and Microsoft Excel format.

Notes.
1. For entry ML7 b.4.b (Agent Orange), there is a discrepancy between the name, which indicates the free acid form, and the CAS number, which indicates the butyl ester form.
2. For entries lacking a CAS registry number, a sequential registry number assinged by Costanzi Research (CR number) is provided instead.
3. For proteins, the UNIPROT ID is provided instead.
4. Overlaps among CWC schedules, Australia Group chemicals, and Wassenaar ML7 chemicals are provided.
5. 2D structures curated by Costanzi Research are provided as SDF and MRV files (MRV files require ChemAxon’s MarvinSketch to open).
6. 3D strucures from PubChem are shown with NCBI’s iCn3D.
7. NIST Chemistry WebBook cards provide chemical and physical data compiled by the National Institute of Standards and Technology, including, inter alia, analytical spectra.
