Novichok
Definition
A class of organophosphate nerve agents developed under the Soviet Union's Foliant programme, structurally distinct from G-series (sarin, tabun, soman) and V-series (VX) agents. Not previously listed in CWC Schedule 1 at the time of the Salisbury attack; subsequently added to Schedule 1 by the Conference of States Parties. Characterised by high acute toxicity and environmental persistence in formulated gel form.

Common questions
Why wasn't Novichok covered by the Chemical Weapons Convention when it was developed?+
The CWC's schedules were built around known agent classes and precursors documented before the programme's existence became public, so its distinct chemical structure fell outside the listed categories until the Salisbury attack drove states parties to add it explicitly.
How did the Salisbury case affect international chemical weapons control?+
It prompted the OPCW's Conference of States Parties to formally add Novichok-type agents to Schedule 1, closing the gap and bringing their production, possession, and precursor trade under the same international controls as other listed nerve agents.
