Bromophenols
A bromophenol is any organobromide of phenol that contains one or more covalently bonded bromine atoms. There are five basic types of bromophenols (mono- to pentabromophenol) and 19 different bromophenols in total when positional isomerism is taken into account. Bromophenols are produced by electrophilic halogenation of phenol with bromine. List of bromophenols There is a total of 19 bromophenols, corresponding to the different ways in which bromine atoms can be attached to the five carbon atoms in the benzene ring of the phenol molecule, excluding the carbon atom to which the hydroxy group is attached. Monobromrophenols have three isomers because there is only one bromine atom that can occupy one of three ring positions on the phenol molecule; 2-bromophenol, for example, is the isomer that has a bromine atom in the '' ortho'' position. Pentabromophenol, by contrast, has only one isomer because all five available ring positions on the phenol are fully brominated. * Monobro ...

Dibromophenol
Dibromophenols form a group of aromatic chemical compounds which are both phenols and bromobenzenes. The structure consists of a benzene ring with an attached hydroxy group (-OH) and two bromine atoms (-Br) as substituents. There are six structural isomer In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature) of a chemical compound, compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct chemical bond, b ...s, each with the molecular formula C6H4Br2O, which differ by arrangement of the substituents.

Monobromophenol
The monobromophenols are chemical compounds consisting of phenol substituted with a bromine atom. There are three isomers, 2-bromophenol, 3-bromophenol, and 4-bromophenol. See also * Bromophenol * Monochlorophenol The monochlorophenols are chemical compounds consisting of phenol substituted with a chlorine atom. There are three isomers, 2-chlorophenol, 3-chlorophenol, and 4-chlorophenol. See also * Chlorophenol A chlorophenol is any organochloride of ph ... References {{reflist Bromoarenes Phenols ...

Chlorophenol
A chlorophenol is any organochloride of phenol that contains one or more covalently bonded chlorine atoms. There are five basic types of chlorophenols (mono- to pentachlorophenol) and 19 different chlorophenols in total when positional isomerism is taken into account. Chlorophenols are produced by electrophilic halogenation of phenol with chlorine. Most chlorophenols are solid at room temperature. They have a strong, medicinal taste and smell. Chlorophenols are commonly used as pesticides, herbicides, and disinfectants. List of chlorophenols There is a total of 19 chlorophenols, corresponding to the different ways in which chlorine atoms can be attached to the five carbons in the benzene ring of the phenol molecule, excluding the carbon atom to which the hydroxy group is attached. Monochlorophenols have three isomers because there is only one chlorine atom that can occupy one of three ring positions on the phenol molecule; 2-chlorophenol, for example, is the isomer that has ...

2,4,6-Tribromophenol
2,4,6-Tribromophenol (TBP) is a brominated derivative of phenol. It is used as a fungicide, as a wood preservative, and an intermediate in the preparation of flame retardants. Production Although natural TBP has been identified in ocean sediments as a metabolite of marine fauna, the commercial product is prepared industrially. In 2001, the production volume of TBP was estimated to be 2500 tonnes/year in Japan and 9500 tonnes/year worldwide. TBP can be prepared by the controlled reaction of elemental bromine with phenol: : Uses The predominant use of TBP is as an intermediate in the preparation of flame retardants such as brominated epoxy resins. TBP is reacted with sodium hydroxide to form the sodium salt, which is used as a fungicide and wood preservative. Bismuth salt The bismuth salt is the active ingredient in Xeroform dressing. Metabolism Microbial metabolism in products treated with TBP is known to produce 2,4,6-tribromoanisole (TBA), which has a musty odo ...
