Bromobenzene is an aryl bromide and the simplest of the bromobenzenes, consisting of a benzene ring substituted with one bromine atom. Its chemical formula is C 6 H 5 Br . It is a colourless liquid although older samples can appear yellow.

1,2,4,5-Tetrabromobenzene is an aryl bromide and a four-substituted bromobenzene with the formula C 6 H 2 Br 4. It is one of three isomers of tetrabromobenzene. The compound is a white solid. 1,2,4,5-Tetrabromobenzene is an important metabolite of the flame retardant hexabromobenzene. [1]
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
Melting point: 18 to 21 °C (64 to 70 °F; 291 to 294 K) [1] Boiling point: 233 to 236 °C (451 to 457 °F; 506 to 509 K) [1] Hazards GHS labelling: Pictograms.
Hexabromobenzene finds extensive use as a fire retardant additive in a range of materials including plastics, paper, and electrical goods, where it serves as a top-tier flame retardant. With an impressive melting point of 327 °C and a high bromide content of 86%, HBB significantly enhances the fire safety of these materials. [12]
Melting point: 5.5 C Water solubility: negligible Specific gravity: 0.87 Principal hazards *** Benzene is a carcinogen (cancer-causing agent). *** Very flammable. The pure material, and any solutions containing it, constitute a fire risk. Safe handling: Benzene should NOT be used at all unless no safer alternatives are available.
