Dehydrobromination, Grignard reactions, reductive coupling, Wittig reaction, and several nucleophilic substitution reactions are some of the principal reactions which involve organic bromides. 90-59-5, formula is C7H4Br2O2, Name is 3,5-Dibromo-2-hydroxybenzaldehyde. Organic compounds having carbon bonded to bromine are called organic bromides. SDS of cas: 90-59-5.
Chinnasamy, Ragaverthini;Munjal, Bhushan;Suryanarayanan, Raj;Peedikakkal, Abdul Malik P.;Mishra, Manish Kumar;Ghosh, Soumyajit research published 《 Pressure and Temperature Induced Dual Responsive Molecular Crystals: Effect of Polymorphism》, the research content is summarized as follows. Dimorphic forms (1a and 1b) of 2-hydroxy-3,5-dibromobenzylidine-4-fluoro-3-nitroaniline (Crystal 1) where form 1a is brittle and form 1b is elastically bendable are reported. Both polymorphs exhibit progressive thermosalient responses which are seemingly different. One polymorph (1a) shows jumping, while the other (1b) shows bending. The property difference is solely attributed to the inherent crystal packing and linked to the differences in the mol. conformations, structural packing, and intermol. interactions. 2-Hydroxy-3-bromo-5-chlorobenzylidine-4-fluoro-3-nitroaniline (Crystal 2) was nonthermosalient but was mech. flexible. Variable temperature powder x-ray diffractometry revealed anisotropic crystallog. face expansion-a possible explanation for the different thermosalient behaviors of the dimorphs.
SDS of cas: 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., 90-59-5.
