Articles & Notes

EA (Experimental Agent) numeric codes were assigned to different groups of substances synthesized or toxicologically tested at Edgewood Arsenal or contracted by companies, universities, and private laboratories. Numbering has been maintained from the 1950s to the present. In addition to experimental chemical agents, codes have been assigned to precursors, degradation products, antidotes, military and industrial toxicants.

The table can be sorted by code number, toxicologic group. Additional data (formula, toxicity) can also be seen by clicking on the name.

The azides of phosphoric and thiophosphoric acids were first synthesized and described in the early '50s and for the next several decades remained in the focus of attention of chemists involved in the development of two related groups of organophosphorus compounds — pesticides and poisoning agents. Their physiological effect is the same as that of G- and V-type chemical warfare agents and is manifested by inhibition of the enzyme cholinesterase.
