Diphenylaminarsincyanid , also known as a Clark III ( C h l or- Ar transmitter K ampfstoff III) is a chemical warfare agent .
Like the warfare agents Clark I and II, which are based on the related diphenylarsine cyanide , it belongs to the so-called blue cross warfare agents and has a strong irritant effect on the nasopharynx (so-called mask breaker ).
The substance forms colorless, garlic-like smelling crystals and causes nausea, vomiting and headaches. Long-term effects are, for example, pulmonary edema.
It was never used and at most it was produced on a pilot plant scale.
