1. When different names are given in different lists, the CWC name is provided first, followed by the alternative name within parentheses.
2. For entries lacking a CAS Registry Number®, a sequential registry number assigned by Costanzi Research (CR number) is provided instead.
3. For proteins, the UNIPROT ID is provided instead.
4. Chemical Weapons Convention (CWC) entry numnber. CWC Schedule 1 entries 1A13 – 1A16 entered into force on June 7, 2020.
5. Australia Group entry number. AG entries 66-87 were added on February 28, 2020.
6. Wassenaar Arrangement (WA) Munitions List 7 (ML7) entry number. For WA 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.
