2,4-Dinitrofluorobenzene Chemical Properties,Usage,Production

Chemical Properties
Yellow solid
Usage
A substituted benzene use in polypeptide sequencing (also referred to as Sanger’s reagent). Used in the derivitization of primary amines. Shown to inhibit the reductase activity of mitochondrial b-c1 complex isolated from beef heart mitochondria.
General Description
Clear yellow crystals or yellow crystalline solid.
Air & Water Reactions
Slightly soluble in water.
Reactivity Profile
Reacts with oxidizing agents . When air was admitted after vacuum evaporation of an ether peroxide solution, a violent explosion occurred. 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.
Fire Hazard
2,4-Dinitrofluorobenzene is probably combustible.
