Methyl bromide is a precursor in the manufacture of several chemicals and is employed as a soil sterilant, mainly for seed production. Formula: C7H4Br2O2.
Majumder, Mitali;Das, Tapashi;Sepay, Nayim;Rajak, Kajal Krishna research published 《 A study of DNA/BSA interaction and catalytic potential of oxidovanadium(V, IV) complexes incorporating dibenzofuran based ON̂Ô ligand》, the research content is summarized as follows. The tridentate Schiff base ligand H2L1, [(Z)-3-((2-hydroxybenzylidene)amino)dibenzo [b,d]furan-2-ol], synthesized by the typical condensation reaction of [3-aminodibenzo[b,d]furan-2-ol] with salicylaldehyde was used in the present work towards the synthesis of mononuclear oxidovanadium complexes. Three mononuclear oxidovanadium complexes [VOL1(OMe)], 1; [VO(L1)(8-Hq)], 2 and [VO(L1)(1,10-phen)], 3 were successfully synthesized with high yield using [VO(acac)2]. 8-Hydroxyquinoline and 1,10-phenanthroline were used as co-ligands in the synthesis of complexes 2 and 3. X-ray crystallog. studies revealed that the ligand H2L1 binds in tridentate fashion. The synthesized complexes were well characterized by using different spectroscopic techniques. The physiochem. properties were well interpreted by d. functional theory (DFT) and time dependent d. functional theory (TDDFT) calculations DNA/BSA interaction study was performed using UV-visible spectroscopy, Fluorescence spectroscopy, CD, viscometer measurements, FRET and Mol. docking study. The complexes bind with DNA through intercalation resulting in shortening of DNA length. Among all the complexes, complex 3 shows the strongest binding ability with DNA and the binding constant (Kb) is 6.2 x 105 M-1. In contrast Complex 2 showed highest binding affinity with the BSA protein (KBSA = 3.7 x 106 M-1). Moreover the energy transfer between BSA and the complexes are feasible in a static quenching interaction. They were also proven to show bromoperoxidase activity with high conversion rate and enhanced selectivity.
90-59-5, 3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes.
3,5-Dibromosalicylaldehyde, also known as 3,5-Dibromosalicylaldehyde, is a useful research compound. Its molecular formula is C7H4Br2O2 and its molecular weight is 279.91 g/mol. The purity is usually 95%.
3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes. 3,5-Dibromosalicylaldehyde can be used in the synthesis of Schiff base and can be used as reactant for synthesis of Schiff base ligands which forms mononuclear complexes with copper(II), nickel(II), zinc(II) and cobalt(II).
3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., Formula: C7H4Br2O2
