Following is the molecular structure of O-dinitrobenzen (528-29-0):

1,2-Dinitrobenzene Uses

O-dinitrobenzen (528-29-0)is used for the synthesis of dyestuffs, dyestuff intermediates, explosives, and celluloid production.

1,2-Dinitrobenzene Production

Reactivity Profile of O-dinitrobenzen (528-29-0): All three isomers have similar properties and may react vigorously with oxidizing materials. Their reaction with nitric acid (nitration) will lead to a mixture of trinitrobenzenes possessing high-explosive properties. If heat and reaction conditions of the nitration are not controlled, detonation comparable to TNT may occur. Mixture of 1,3-dinitrobenzene with tetranitromethane was found highly explosive. 1,2-dinitrobenzene is a severe explosion hazard when shocked or exposed to heat or flame. When heated to decomposition all dinitrobenzens emit toxic fumes of nitrogen oxides.

1,2-Dinitrobenzene Safety Profile

Suspected carcinogen. Poison by inhalation and ingestion. Moderately toxic by skin contact. Can cause liver, kidney, and central nervous system injury. Combustible when exposed to heat or flame; can react vigorously with oxidizing materials. A severe explosion hazard when shocked or exposed to heat or flame. It is used in bursting charges and to fill artillery shells. Mixtures with nitric acid are highly explosive. To fight fire, use water, CO₂, dry chemical. Dangerous; when heated to decomposition it emits highly toxic fumes of NO_x and explodes.
