4-Amino-3-bromophenol (cas: 74440-80-5) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon闂佺偨鍎茶ぐ绲﹐mine bond is electrophilic, i.e. alkyl bromides are alkylating agents. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Recommanded Product: 74440-80-5

4-Amino-3-bromophenol (cas: 74440-80-5) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Related Products of 74440-80-5

Heterocycle Annulation of Enolizable Vinyl Quinone Imides.

And the article was included in Organic Letters in 2002.Related Products of 74440-80-5 This article mentions the following:

Enolizable vinyl quinone mono- and diimide substrates I (R = Ac, Me3SiCH2CH2SO2; X = O, NR) undergo cyclization in toluene with HMPA in the dark to provide protected 6-hydroxy and 6-amino dihydroquinolines II (R = Ac, Me3SiCH2CH2SO2; X = O, NR) in 55-71% yields. Aromatization of I (R = Ac, Me3SiCH2CH2SO2; X = O, NR) provides the corresponding quinolines upon deprotection of the dihydroquinoline nitrogens. The substrates I are prepared from bromophenylenediamines and bromoaminophenols using a Stille coupling to assemble the framework followed by deprotection (if needed) and oxidation to generate the quinone imides. When the quinone monoimides I (R = Ac, Me3SiCH2CH2SO2; X = O) are stirred in toluene with HMPA under ambient light, the hydroxyindoles III (R = Ac, Me3SiCH2CH2SO2) are obtained instead in 59-69% yields.

4-Amino-3-bromophenol (cas: 74440-80-5) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others.

Synthesis of new dinuclear and mononuclear peroxovanadium(V) complexes containing biogenic co-ligands: a comparative study of some of their properties was written by Sarmah, Swapnalee;Kalita, Diganta;Hazarika, Pankaj;Borah, Ruli;Islam, Nashreen S.. And the article was included in Polyhedron in 2004.Recommanded Product: 4-Amino-3-bromophenol This article mentions the following:

Dinuclear peroxo complexes of vanadium, [V2O2(O2)3(asn)3]閻犺櫣鏋?sub>2O (1, asn = asparagine) and [V2O2(O2)3(gln)3]閻犺櫣鏋?sub>2O (2, gln = glutamine) were synthesized from the reaction of V2O5 with H2O2 and the resp. amino acid ligand at pH 闂?. Similar reactions conducted at pH 闂? afforded the monomeric complexes, Na[VO(O2)2(asn)]閻犺櫣鏋?sub>2O (3) and Na[VO(O2)2(gln)]閻犺櫣鏋?sub>2O (4). The compounds were characterized by elemental anal. and spectral studies. In complexes 1 and 2, the two V(V) centers are bridged by a peroxo group and an amino acid ligand occurring as a zwitterion. The monomeric complexes 3 and 4 contain peroxo groups bonded in a side-on fashion and an amino acid co-ligand binding the V(V) center through O (carboxylate) atoms. The complexes 1 and 2 rapidly degraded in aqueous solution with release of O2 and formation of diperoxovanadate and decavanadate as shown by 51V NMR spectra whereas complexes 3 and 4 remained stable in solution for over 24 h. Extent and rate of O2 released from the two types of complexes under the effect of catalase action further evidenced the differences in their V:O22- content and mode of peroxide binding in these species. The 婵?peroxovanadate complexes 1 and 2 instantaneously oxidized bromide to a bromination-competent intermediate in phosphate buffer at physiol. pH, and also efficiently mediated bromination of organic substrates in aqueous-organic media. Complexes 3 and 4 were inactive for bromination under analogous conditions. These findings make the dinuclear complexes 1 and 2 possible candidates of mimic in the action of vanadium in bromoperoxidase.
