On February 28, 2020, 24 Novichok precursors were added to the Australia Group (AG) Chemical Weapons Precursors list, to complement the recent addition of Novichok agents to CWC Schedule 1.

The added Novichok precursors include AG entries 66-72 – phosphorus-containing precursors for the synthesis of phosphate agents listed in CWC 1A14, e.g. A-232 and A-234 – and AG entries 73-89 – amidine precursors for the synthesis of CWC 1A13 and CWC 1A14. The phosphorus-containing precursors for the synthesis of the phosphonate agents listed in CWC 1A13 (e.g. A-230) and CWC 1A15 (A-242) were already part of the AG chemical precursors list prior to the amendment, as they coincide with the precursors for canonical nerve agents.

The table below lists the new entries added to the AG Chemical Weapons Precursors list, curated and structurally annotated.

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