The starting material for the synthesis of brominated fatty acids were oleic acid. The oleic acid was analysed by using Gc to contain predominantly 96.6% of c18:1 and 3.4% of c18:2. oleic acid was reacted with hydrogen bromide to give the alkyl halide. The double bond at position 9 of the hydrocarbon backbone is a source that is rich in π

Brominated aromatic compounds including bromophenols are hazardous and are being fast recognized as priority pollutants. We present here a novel photo-Fenton based degradation system using selenium doped copper oxide nanoparticles (Se-doped CuO NPs)/H 2 O 2 /UV, which facilitated 99.5% degradation of 4-bromophenol in 90 min at a rate of 0.057 min −1.
Halide vacancies and associated metallic lead (Pb°) observed at the surface and deep inside macroscopic organolead trihalide perovskite crystals is removed through a facile and noninvasive treatment. Indeed, Br2 vapor is shown to passivate Br-vacancies and associated Pb° in the bulk of macroscopic crystals. Controlling the exposure time can markedly improve the overall stoichiometry …

Brominated Lipids. Avanti offers several brominated fatty-acid modified phosphatidylcholine (PC) derivatives. These brominated PCs are especially useful for investigating the structure of membrane-bound proteins using fluorescence quenching techniques. Brominated PCs are used as the fluorescent quencher in fluorescent quenching techniques.
The anionic MOF contains dimethyl amine cations in its pores which, owing to their pre-bonded C–N moiety, act as a precursor for N-doping of the carbon dots. The N-doped carbon dots are held together by graphitic stacking and they show electrocatalytic activity as a metal-free catalyst for the oxygen reduction reaction (ORR).
