3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.

Amphiphilic dendrimers with heteroleptic bis([2,2′:6′,2”]terpyridine)-ruthenium(II) cores was written by Joester, Derk;Gramlich, Volker;Diederich, Francois. And the article was included in Helvetica Chimica Acta in 2004.Category: bromides-buliding-blocks This article mentions the following:

Dendrimers were assembled through formation of homo- and heteroleptic RuII complexes with [2,2′:6′,2”]terpyridine ligands bearing hydrophilic and hydrophobic dendrons (I; R = C12H25 (11), C(CH2CH2CO2But)3 (13), C(CH2CH2CONHC12H25)3 (14)), with the aim to develop amphiphilic vectors for potential use in gene delivery (Scheme 1). The synthesis started with the preparation of the 4′-(3,5-dihalo-4-methoxyphenyl)-[2,2′:6′,2”]terpyridine ligands via the Kroehnke pyridine synthesis, followed by attachment of dendrons by Sonogashira cross-coupling to give the dendritic ligands I (R = C12H25, C(CH2CH2CO2But)3, C(CH2CH2CONHC12H25)3, C(CH2CH2CO2tBu)3, C(CH2CH2CONHC(CH2XH2NHBoc)3)3, c(CH2CH2CONHC(CH2CH2CONHC12H25)3)3). Ligands were subsequently introduced into the coordination sphere of RuIII to give the stable intermediates [Ru(11)Cl3] (24) and [Ru(14)Cl3] (27). These were transformed under reductive conditions into the heteroleptic complexes [Ru(11)(13)](PF6)2 (25) and [Ru(13)(14)](PF6)2 (29). Removal of the (tert-butoxy)carbonyl (Boc) protecting groups in 25 and 29 then gave the desired amphiphilic dendrimers with branchings of generations 0 and 1. Complex formation was analyzed by high-resolution matrix-assisted laser-desorption-ionization Fourier-transform ion-cyclotron-resonance mass spectrometry (HR-MALDI-FT-ICR-MS), which provided spectra featuring unique fragment-ion series and perfectly resolved isotope distribution patterns. The preparation of homo- and heteroleptic complexes with terpyridine ligands bearing generation-2 dendrons failed due to steric hindrance by the bulky wedges. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1Category: bromides-buliding-blocks).
