Chloride substituents modify the physical properties of organic compounds in several ways. 6334-18-5, formula is C7H4Cl2O, Name is 2,3-Dichlorobenzaldehyde. They are typically denser than water due to the presence of chlorine, which has a high atomic weight. Application of C7H4Cl2O.
Bukowska, Agnieszka;Bester, Karol;Pytel, Maciej;Bukowski, Wiktor research published 《 Polymer Beads Decorated with Dendritic Systems as Supports for A3 Coupling Catalysts》, the research content is summarized as follows. The gel type microscopic polymer beads bearing epoxy functionalities were modified using the two-stage procedures in order to decorate their surface with the moieties of the zeroth order PAMAM type dendrimer and different heterocyclic aldehydes (2-pyridinecarboxaldehyde, 2-pyrrolidinecarboxaldehyde, furfural or 2-thiophenecarboxaldehyde). The polymeric supports provided in this manner were then used for the immobilization of copper(II) ions. The resulting materials were characterized using different instrumental techniques (optical microscopy, SEM, FTIR microscopy, DR UV-Vis, ICP-OES, and thermal anal.). They were also used as catalysts in the model A3 coupling reaction of benzaldehyde, morpholine and phenylacetylene. The best catalytic activity was found for the polymeric catalyst bearing 2-pyridinecarboxaldehyde moieties. It turned out to be effective in the A3 coupling reactions included different benzaldehyde, alkyne, and secondary amine derivatives, as well. It could also be recycled several times without a significant decrease in its activity in the model A3 coupling reaction.
Application of C7H4Cl2O, 2,3-Dichlorobenzaldehyde(2,3-DBA)is a useful research compound. Its molecular formula is C7H4Cl2O and its molecular weight is 175.01 g/mol. The purity is usually 95%.
2,3-DBA is an organic compound that is used as a synthetic intermediate in the preparation of other chemicals. It is prepared by reacting 2-chloroacetophenone with hydrochloric acid and sodium carbonate in a reaction vessel. The product can be purified through fractional distillation or crystallization. The optical properties of 2,3-DBA are determined by its dipole moment and the substituents attached to the methylene group. Molecular modeling studies have shown that felodipine can bind to 2,3-DBA through its active methylene group. The reaction products between sulfadiazine and 2,3-DBA are pyridinedicarboxylic acid and 3-chlorobenzaldehyde.
2,3-DBA is part of a group of Benzaldehyde (B119740) derivatives that exhibit activity against Mycobacterium tuberculosis, the bacteria responsible for causing tuberculosis in humans. 2,3-DBA is also used as a reagent to synthesize (E)-2-(2-arylhydrazinyl)quinoxalines, compounds that have potent anticancer activity., 6334-18-5.
