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. It is used in organic synthesis of pharmaceuticals, agrochemicals and fire-extinguishing agents.
Brominating aniline with elemental bromine gives 2,4,6-tribromoaniline. This is then diazotized, then reacted with ethanol to replace the diazonium group with hydrogen, forming 1,3,5-tribromobenzene. [3] It has also been prepared by these methods: [3] replacement of the amino group of 3,5-dibromoaniline with bromine
The bromoanilines form a group of three isomers where the bromine atom occupies the para, ortho or meta position on the aromatic ring. Bromoaniline isomers Arene substitution patterns. The three isomers are: 2-Bromoaniline (o-Bromoaniline) [1] 3-Bromoaniline (m-Bromoaniline) [2] 4-Bromoaniline (p-Bromoaniline) [3]
4-Bromoaniline is a compound where an aniline molecule is substituted with a bromine atom on the para position. Commercially available, this compound may be used as a building block, e.g. in the preparation of monobrominated biphenyl via the Gomberg-Bachmann reaction. [2]
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
PBr 3 is prepared by treating red phosphorus with bromine. An excess of phosphorus is used in order to prevent formation of PBr 5: [1] [2] P 4 + 6 Br 2 → 4 PBr 3. Because the reaction is highly exothermic, it is often conducted in the presence of a diluent such as PBr 3. Phosphorus tribromide is also generated in situ from red phosphorus and ...

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.
