Schedule 1 Chemical Agent Law and Legal Definition

Pursuant to 22 USCS § 6701 (10) [Title 22. Foreign Relations and Intercourse; Chapter 75. Chemical Weapons Convention Implementation], the term Schedule 1 chemical agent means “any of the following, together or separately:

(A) O-Alkyl ( <- C[10] incl. cycloalkyl) alkyl

(Me, Et, n-Pr or i-Pr)-phosphonofluoridates

(e.g. Sarin: O-Isopropyl methylphosphonofluoridate Soman: O-Pinacolyl methylphosphonofluoridate).

(B) O-Alkyl ( <- C[10] incl. cycloalkyl) N,N-dialkyl

(Me, Et, n-Pr or i-Pr)-phosphoramidocyanidates

(e.g. Tabun: O-Ethyl N,N-dimethyl phosphoramidocyanidate).

(C) O-Alkyl (H or <- C[10] incl. cycloalkyl) S-2-dialkyl

(Me, Et, n-Pr or i-Pr)-aminoethyl alkyl

(Me, Et, n-Pr or i-Pr) phosphonothiolates and corresponding alkylated or protonated salts

(e.g. VX: O-Ethyl S-2-diisopropylaminoethyl methyl phosphonothiolate).

(D) Sulfur mustards:


Mustard gas: (Bis(2-chloroethyl)sulfide


Sesquimustard: 1,2-Bis(2-chloroethylthio)ethane





O-Mustard: Bis(2-chloroethylthioethyl)ether.

(E) Lewisites:

Lewisite 1: 2-Chlorovinyldichloroarsine

Lewisite 2: Bis(2-chlorovinyl)chloroarsine

Lewisite 3: Tris (2-clorovinyl)arsine.

(F) Nitrogen mustards:

HN1: Bis(2-chloroethyl)ethylamine

HN2: Bis(2-chloroethyl)methylamine

HN3: Tris(2-chloroethyl)amine.

(G) Saxitoxin.

(H) Ricin.

(I) Alkyl (Me, Et, n-Pr or i-Pr) phosphonyldifluorides

(J) O-Alkyl (H or <- C[10] incl. cycloalkyl)O-2-dialkyl

(Me, Et, n-Pr or i-Pr)-aminoethyl alkyl

(Me, Et, n-Pr or i-Pr) phosphonites and corresponding alkylated or protonated salts

e.g. QL: O-Ethyl O-2-diisopropylaminoethyl methylphosphonite.

(K) Chlorosarin: O-Isopropyl methylphosphonochloridate.
