2,4-Dinitrobromobenzene is a useful organic intermediate and is readily prepared in a laboratory.
Contents
Properties
Chemical
2,4-Dinitrobromobenzene is soluble in water and methanol. It is reactive towards reducing agents such as Sn/HCl and H2/Pd to form 2,4-diaminobromobenzene.
Physical
2,4-Dinitrobromobenzene, when pure, is a light yellow crystalline substance which melts at 71°C-73°C. It has the characteristic slightly sweet smell of nitroaromatic compounds, though it is toxic and inhalation of the dust should be avoided. It has a density of 1.91 g/cm3.
Availability
2,4-Dinitrobromobenzene is not offered by any suppliers available to the amateur. However, 2,4 dinitrochlorobenzene may be available from chemical suppliers and finds similar uses.
Preparation
2,4-Dinitrobromobenzene can be prepared with relative ease in a home lab by the nitration of bromobenzene. A writeup of this reaction is available here.
Projects
- Preparation of 2,4-Dinitrophenol as a precursor to DNPO
- Preparation of 2,4-Dinitrophenylhydrazine
Safety
2,4-Dinitrobromobenzene is a mutagen and skin irritant. Skin contact should be avoided by wearing gloves as some people possess a severe allergy to the compound, resulting in contact dermatitis of varying severity. It may have shock sensitivity, though the extent of which is currently undocumented.
