  Chemical Weapons Information - Federation of American Scientists
Chemical weapons use the toxic properties of chemical substances rather than their explosive properties to produce physical or physiological effects on an enemy.
Although instances of what might be styled as chemical weapons date to antiquity, much of the lore of chemical weapons as viewed today has its origins in World War I. During that conflict "gas" (actually an aerosol or vapor) was used effectively on numerous occasions by both sides to alter the outcome of battles.
Chemical weapons were never deliberately employed by the Allies or the Axis during World War II, despite the accumulation of enormous stockpiles by both sides.

Indeed, one definition of chemical informatics is "the mixing of information resources to transform data into information and information into knowledge, for the intended purpose of making decisions faster in the arena of drug lead identification and optimization." Now chemical informatics is being applied to problems across the full range of chemistry.
The ability to search large secondary databases such as Chemical Abstracts or Medline easily and precisely and to move s eamlessly back and forth between the original primary journal literature and the abstracting and indexing databases is one of the truly great achievements of modern chemical informatics research.
Not only can chemical structures be used as search keys in such systems, but also unknown properties and spec tra can be predicted using chemical informatics tools and techniques that draw on the existing knowledge base of chemistry.

 Chemical Weapons, Nuclear War - by Jorge Hirsch
As the U.S. bombers are about to take off, there will be no time to talk about the fact that Iran has signed and ratified the Chemical Weapons Convention (in 1993 and 1997, respectively) that requires it to terminate production and eliminate stockpiles over a period of years.
Instead, it will be emphasized that Iran used chemical weapons in the Iran-Iraq war (conveniently omitting the fact that it was responding to chemical attacks by Iraq) and that it could use them again against U.S. troops next door.
Given these prospects, the U.S. should be focusing on low-key negotiations with Iran to reach a mutually acceptable agreement with respect to Iran's nuclear ambitions (which are, at least in the view of Russia and China, entirely legitimate), instead of issuing strident denunciations.
