Microbial metabolism in products treated with TBP is known to produce 2,4,6-tribromoanisole (TBA), [9] which has a musty odor. In 2010 and 2011, Pfizer and Johnson & Johnson voluntarily recalled some products due to TBA odors from wooden pallets which were treated with TBP. [10] [11] [12] [13]
Infobox references. 2,4,6-Tribromoanisole (TBA) is a chemical compound that is a brominated derivative of anisole. It is one of the chemicals responsible for cork taint. [2] Tribromoanisole is a fungal metabolite of 2,4,6-tribromophenol, which is used as a fungicide. It can be found in minute traces on packaging materials stored in the presence ...
Properties. 2,4,6-Tri- tert -butylphenol is a white solid which dissolves in many organic solvents, but not in aqueous or alcoholic alkaline solutions. The green-blue coloring with iron (III)chloride, which is characteristic for phenols, does not occur in 2,4,6-TTBP. The compound is oxidizable in air but practically non-biodegradable.
A bromophenol is an organic compound consisting of hydroxyl groups and bromine atoms bonded to a benzene ring. They may be viewed as hydroxyl derivatives of bromobenzene, or as brominated derivatives of phenol. There are five basic types of bromophenols (mono- to pentabromophenol) and 19 different bromophenols in total when positional isomerism ...
The reaction in figure 2 shows the reductive debromination of 2,4,6-tribromophenol (2,4,6-TBP) by Ochrabactrum. [13] Based on the relative degradation of the molecule along with analytical results, it has been postulated that degradation of 2,4,6-TBP proceeds through debromination of ortho -bromine in the first step by a dehalogenase to yield 2 ...
2,4,6-Tribromoaniline. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 2,4,6-Tribromoaniline is a brominated derivative of aniline with the formula C 6 H 4 Br 3 N. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents.
Dibromophenol. Dibromophenols are a group of bromophenols consisting of one hydroxy group and two bromine atoms bonded to a benzene ring. There are six structural isomers, each with the molecular formula C 6 H 4 Br 2 O, which differ by arrangement of the substituents. Dibromophenols.
Infobox references. 2,4,6-Tri-tert-butylpyrimidine is the organic compound with the formula HC (Bu t C) 2 N 2 C t Bu where t Bu = (CH 3) 3 C. It is a substituted derivative of the heterocycle pyrimidine. Known also as TTBP, this compound is of interest as a base that is sufficiently bulky to not bind boron trifluoride but still able to bind ...
