Reactivities / Incompatibilities

Incompatible materials: Oxidizing agents, iron, zinc, copper, silver/silver oxides, cadmium/cadmium oxides, alcohols, acids, halogens, aldehydes.
Shock-sensitive compounds may be formed with gold, halogens, mercury, mercury oxide, and silver oxide.
Attacks some coatings, plastics, rubber, copper, brass, bronze. aluminum, steel, tin, zinc, and their alloys.
Potentially violent or explosive reactions on contact with interhalogens (e.g., bromine pentafluoride, chlorine trifluoride), 1,2-dichloroethane (with liquid ammonia), boron halides, chloroformamideium nitrate, ethylene oxide (polymerization reaction), magnesium perchlorate, nitrogen trichloride, oxygen + platinum, or strong oxidants (e.g., potassium chlorate, nitryl chloride, chromyl chloride, dichlorine oxide, chromium trioxide, trioxygen difluoride, nitric acid, hydrogen peroxide, tetramethylammonium amide, thiocarbonyl azide thiocyanate, sulfinyl chloride, thiotriazyl chloride, ammonium peroxodisulfate, fluorine, nitrogen oxide, dinitrogen tetraoxide, and liquid oxygen).
Incompatible in contact with /silver/, acetaldehyde, acrolein, /boron/, /boron triiodide/, halogens, /chloric acid/, /chlorine monoxide/, chlorites, chlorosilane, (ethylene dichloride + liquid ammonia), /gold/, hexachloromelamine, (hydrazine + alkali metals), /hydrogen bromide/, /hypochlorous acid/, /magnesium perchlorate/, /dinitrogen tetroxide/, /nitrogen trichloride/, /nitrogen trifluoride/, /oxygen difluoride/, /phosphorus pentoxide/, /phosphorus dioxide/, picric acid, (/potassium/ + /arsine/), (/potassium/ + /phosphine/), (/potassium/ + /sodium nitrite/), potassium ferricyanide, potassium mercuric cyanide, (/sodium/ + /carbon monoxide/), /antimony/, /sulfur/, /sulfur dichloride/, tellurium hydropentachloride, trichloromelamine, /nitryl chloride/, /stibine/, tetramethylammonium amide, /thionyl chloride/, and thiotrithiazylchloride.
Strong oxidizers, acids, halogens, salts of silver and zinc [Note: corrosive to copper and galvanized surfaces].
With picric acid: Forms explosive salts.
In reactions between bromine pentafluoride and acetic acid, ammonia, benzene, cellulose (in paper), ethyl alcohol, organic matter such as grease or wax, hydrogen sulfide, or methane, fire and explosions are likely.
Reacts with acids and oxidizing materials. Corrosive to copper, zinc, and many metal surfaces.
