Stability::    Stable. Incompatible with strong oxidizing agents, bases, amines, moisture, alcohols. Corrodes steel. Reacts slowly with water. Combustible.
Chemical Properties
white to light yellow crystal powde
General Description
Solid.
Air & Water Reactions
May react slowly with water.
Reactivity Profile
Incompatible with sodium hydroxide. [EPA, 1998]. A halogenated aromatic nitro compound. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
Health Hazard
Poisonous if swallowed or dust is inhaled.
Fire Hazard
Incompatible with sodium hydroxide.
