@alexghionis @rusembassynl In entry 1 of EC-M-62/DEC.1, "phosphoramidic" was a typo (you can clearly see this from the listed example, which is a "phosphonamidic" fluoride derivative). The two elements of the joint proposal feature phosphonamides and phosphoramides, respectively.

@alexghionis @rusembassynl The consolidated list has the two elements of the joint American-Canadian-Dutch proposal (entry 1 and entry 2) plus elements 3 and 4 of the Russian proposal (entry 3 and 4).

The Russian Federation’s decision to drop part of its proposal should smooth the path to a positive vote on the adoption of both sets of proposals by the Conference of State Parties to the Chemical Weapons Conventions next November.

...Russia dropped the fifth component of its original proposal, which contained chemicals that the @OPCW Technical Secretariat determined did not meet the criteria for inclusion in Schedule 1.

According to the CWC's provisions, any weapon that exploits the toxicity of chemicals to intentionally kill of harm humans or animals is considered a chemical weapon.

It is worth clarifying the the CWC Schedules serve the purpose of supporting the Convention's verification regime and should not be interpreted as a list of all chemical warfare agents.
