Chloroacetophenone used as tear gas for riot control ...

CONT

CN gas, or chloroacetophenone or phenacyl chloride, is a substance used as a riot control agent. ... It was investigated, but not used, during the First and Second World Wars, and was used by United States forces in Vietnam. Because of its greater toxicity, it has largely been supplanted by CS gas. CN is still supplied to paramilitary and police forces in a small pressurized aerosol can known as "Mace" or tear gas. Its use has fallen by the wayside as pepper spray works faster and disperses more quickly than CN.

OBS

Like CS gas, this [CN gas] irritates the mucous membranes (oral, nasal, conjunctival and tracheobronchial). Sometimes it can give rise to more generalized reactions such as syncope, temporary loss of balance and orientation. More rarely, cutaneous irritating outbreaks have been observed and allergic contact permanent dermatitis.
