2,4-Dinitrobromobenzene

2,4 Dinitrobromobenzene is a useful organic intermediate and easier to prepare in a home lab than 2,4 dinitrochlorobenzene.

Properties

Chemical

2,4 Dinitrobromobenzene is soluble in water and methanol.

Physical

2,4 Dinitrobromobenzene is an off-white crystalline stubstance that, when pure, melts at 71°C-73°C. 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 this compound finds very similar uses.

Preparation

2,4 Dinitrochlorobenzene can be prepared with relative ease in a home lab by nitrating 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. It may have shock sensitivity, though there are no good references on this.
