Properties
Melting Point: 204
Stability:No data.
Solubility:Very soluble in water and ethanol
Appearance:Brown to dark brown microcrystalline powder.
Specification:

1.Air & Water Reactions: Sodium-4-(2,4-dinitroanilino)diphenyl-amine-2-sulfonate (6373-74-6) is slightly soluble in water.
2.Reactivity Profile: Organonitrates 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. Nitroalkanes are milder oxidizing agents, but still react violently with reducing agents at higher temperature and pressures.
3.Health Hazard: acute/chronic hazards: When heated to decomposition Acid Orange 3 emits highly toxic fumes of SOx, NOx and Na2O.
4.Fire Hazard :Flash point data for Acid Orange 3 are not available; however, Acid Orange 3 is probably combustible.
