What is Dibenz-(b,f)-1,4-oxazephine ?
Description
Agent CR, dibenz-(b,f)-1,4-oxazepine, is a pale-yellow, crystalline solid, which has a melting point of 163°F (72°C). It has a pepper-like odor and is only used in solution for dissemination in liquid dispensers. Solutions consist of 0.1% of CR in 80 parts of propylene glycol and 20 parts water. CR is an eye irritant in organic solutions at concentrations of 0.0025% or lower. Agent CR is less toxic when inhaled, but has more profound skin effects, which are longer lasting. It is a persistent agent when released in the environment and deposited on clothing.
General Description
Colorless liquid, odorless to fruity.
Reactivity Profile
As an amine, Dibenz-(b,f)-1,4-oxazephine probably behaves less as a base than other aliphatic amines as due to Dibenz-(b,f)-1,4-oxazephine cyclic structure. However Dibenz-(b,f)-1,4-oxazephine will react as a weak base.
Health Hazard
Median incapacitating dose: 0.15. Eye/skin toxicity: Highly irritating; not toxic. Rate of action: Instantaneous. Physiological action: Irritates skin, eyes, nose, and throat. Detoxification rate: Moderate. (ANSER)
Safety Profile
Poison by intraperitoneal and intravenous routes. Moderately toxic by ingestion and inhalation. Experimental teratogenic and reproductive effects. A human skin and eye irritant. Questionable carcinogen with experimental carcinogenic and tumorigenic data. When heated to decomposition it emits toxic fumes of NOx.
