Stability and reactivity

Stability

Stability

Although it is stable in the dry state, if it is wet or dissolved in water, It generates hypochlorous acid.

Reactivity

Heating / combustion	There is a danger. It decomposes to produce chlorine, carbon monoxide, nitrogen trichlorideGenerate toxic gas.
Water	There is a danger. It hydrolyzes to generate hypochlorous acid. When reacting with a small amount of water, reaction heat accumulates, there is a danger of fire or toxic gas generation.
Air	No risk
Incompatible	There is a danger. It decomposes when mixed with acid, alkali, reducing substances, fats and oils, other oxidizing agent (bleaching powder, sodium hypochlorite) or the like, it generates toxic gases such as chlorine, carbon monoxide and nitrogen trichloride. There is a danger of explosion as the concentration of nitrogen trichloride increases.
Conditions to Avoid	Mixed contact with other substances and heat and humidity
Hazardous decomposition products	Chlorine, carbon monoxide, nitrogen trichloride etc.
Incompatible hazardous substance	Flammable substances and reducing substances. Ammonia, ammonium salts and amines, sodium carbonate (soda ash)

Handling and Storage Precautions

Handling

Technical measures	Reduce gas divergence as much as possible, and use protective gear, protective eyeglasses, rubber gloves, dust mask etc. Install a local exhaust system.
Notes	Handle the container carefully, scatter it or waste liquid into a special container. Collect it.
Safety Handling Precautions	Fire, heat, alkalis, organic solvents, reducing substances and other combustible substances. Avoid contact. Contact with advanced bleaching powder, ammonia and its salts is an explosive. There is a danger.

Storage

Proper storage condition	Isolate from those described in "Safety Handling Precautions", seal it in a cold-drying place store. Storage under nitrogen gas is desirable.
Safe containers and packaging materia	Poly container, glass, pottery etc. (Metals are corroded)
