2,4-Dibromobiphenyl is an organic compound which is used in a wide variety of industrial and commercial applications. It is a colourless to pale yellow crystalline solid which has a molecular formula of C12H7Br2.

2,4-Dibromobiphenyl is primarily used as an intermediate in the synthesis of various other organic compounds. It is used to manufacture various dyes, pigments, agrochemicals, and pharmaceuticals. It is also used as a flame retardant, and in the production of rubber and plastics.

2,4-Dibromobiphenyl is produced by the bromination of 2,4-dichlorobiphenyl. The reaction is conducted in the presence of a catalyst, typically aqueous sulfuric acid, and is often carried out at temperatures of around 100-200°C. The reaction yields a mixture of 2,4,5-tribromobiphenyl and 2,4-dibromobiphenyl, which must be separated by distillation, column chromatography, or other processes.

2,4-Dibromobiphenyl is generally supplied in the form of a white to yellowish-brown crystalline powder. It is highly soluble in organic solvents such as chloroform, ethyl acetate, and acetone, and is slightly soluble in water. It has a melting point of around 98-100°C and a boiling point of around 250-251°C.

2,4-Dibromobiphenyl is relatively stable when stored in cool, dry conditions, and it should not be exposed to temperatures above 100°C or direct sunlight. It should also be kept away from sources of ignition, as it is combustible and may react violently with oxidizing agents.

2,4-Dibromobiphenyl is toxic when ingested, inhaled, or absorbed through the skin. It is also corrosive and may cause skin burns. As such, it should only be handled with appropriate safety equipment such as gloves, safety glasses, and protective clothing. Additionally, it should be disposed of in accordance with local regulations.
