4-Bromophenol is a pinkish-brown crystalline solid. four-sided biconical crystal precipitated from ether or chloroform. The melting point is 66.4 ℃, and a small amount of water can reduce the melting point a lot. Soluble in water, chloroform, easily soluble in ethanol, ether and glacial acetic acid, soluble in 7 parts of water.
4-Bromophenol is used as an intermediate in medicine grade. It is also used as a phenol that is used in Stille reactions. It is used in the intermediate of organic synthesis, flame retardant and pharmaceutical industry.
4-Bromophenol is a phenolic derivative that It can used as a reagent in Stille reactions or Intermediates of Liquid Crystals.
4-Bromophenol is synthesized by bromination of phenol. The bromine and carbon disulfide solution was added to the phenolic carbon disulfide solution, and the addition was started below 5°C, and the addition was completed under stirring for 2 hours. Phenol and bromine are approximately equimolar ingredients. Distill the reactant to remove carbon disulfide, and then conduct fractional distillation under reduced pressure to collect fractions at 145-150°C (3.32-3.99kPa) to obtain the product. Yield 80-84%.
ChEBI: 4-bromophenol is a bromophenol containing only hydroxy and bromo substituents that are para to one another. It has a role as a mouse metabolite, a persistent organic pollutant, a human xenobiotic metabolite, a rat metabolite, a human urinary metabolite and a marine metabolite.
Crystallise the phenol from CHCl3, CCl4, pet ether (b 40-60o), or water and dry it at 70o under vacuum for 2hours. [Beilstein 6 IV 1043.]
