1Bromo3nitrobenzene

1-Bromo-3-nitrobenzene is an organic compound with the chemical formula C6H4BrNO2. It is a derivative of benzene, where one hydrogen atom is replaced by a bromine atom and another hydrogen atom is replaced by a nitro group. This compound is a colorless liquid at room temperature, with a boiling point of approximately 240°C.

1-Bromo-3-nitrobenzene is primarily used as an intermediate in the synthesis of other organic compounds. Its nitro group can undergo various reactions, such as reduction to an amino group or substitution reactions with nucleophiles. The bromine atom can also be substituted in nucleophilic substitution reactions.

The compound is typically prepared by the nitration of 1-bromobenzene using a strong nitrating agent, such as a mixture of nitric and sulfuric acids. The reaction proceeds via electrophilic aromatic substitution, where the nitro group is introduced ortho to the bromine atom.

1-Bromo-3-nitrobenzene is a hazardous substance. It is toxic if swallowed, inhaled, or absorbed through the skin. It is also a potential carcinogen, and prolonged exposure should be avoided. Proper personal protective equipment, such as gloves, safety glasses, and a lab coat, should be worn when handling this compound. It should be stored in a cool, dry, well-ventilated area away from incompatible substances.
