An interesting alternative synthesis of thissubstance starts by sequential reaction of N-benzylaniline with phosgene, and then with sodium azide to product the corresponding carbonyl azide.
Additionally, chemical burns can be caused by some types of cytotoxic chemical weapons, e.g., vesicants such as mustard gas and Lewisite,or urticants such as phosgene oxime.

Among the weapons in the German arsenal was the newly-invented flammenwerfer, or flamethrower;that year also saw the first use by the Germans of phosgene gas, ten times more lethal than the chlorine gas they previously used.
Although less dangerous than many other chemical weapons,such as sarin, phosgene is still regarded as a viablechemical warfare agent because it is so easy to manufacture when compared to the production requirements of more technically advanced chemical weapons such as the first-generation nerve agent tabun.[7].
To make matters worse, the Germans unleashed 2,000 tons of poisonous gas-including mustard and phosgene gas- against the British at the Lys, incapacitating 8,000(of whom many were blinded) and killing 30.
