1,5-Dibromo-2,4-dinitrobenzene(CAS: 24239-82-5)

1,5-Dibromo-2,4-dinitrobenzene is a crystalline compound with a molecular weight of approximately 329.05 g/mol. It has a low solubility in water but is more soluble in organic solvents like acetone and methanol. The compound is known for its high reactivity, particularly towards nucleophiles. It exhibits strong absorption in the UV region, which can be used for spectroscopic analysis.

1,5-Dibromo-2,4-dinitrobenzene is typically synthesized through the sequential bromination and nitration of benzene. This involves first nitration of benzene to form 2,4-dinitrobenzene, followed by bromination of the meta position to yield 1,5-dibromo-2,4-dinitrobenzene. The reaction conditions include the use of concentrated sulfuric acid and fuming nitric acid for nitration, and bromine in carbon tetrachloride for bromination.

1,5-Dibromo-2,4-dinitrobenzene is used in the pharmaceutical industry for the synthesis of certain drugs, and in the semiconductor industry for the production of organic semiconductors. It also has applications in the polymer industry for the synthesis of functional polymers and in the field of sensors for its unique reactivity.

When handling 1,5-Dibromo-2,4-dinitrobenzene, it is essential to wear proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate chemical spill kits and the area should be left to air out. Always consult the Safety Data Sheet (SDS) for detailed handling and disposal information.
