Kurnia, Kiki Adi;Setyaningsih, Widiastuti;Darmawan, Noviyan;Yuliarto, Brian research published 《 A comprehensive study on the impact of the substituent on pKa of phenylboronic acid in aqueous and non-aqueous solutions: A computational approach》, the research content is summarized as follows. The acid dissociation constant (pKa) is the fundamental physicochem. properties required to understand the structure and reactivity of boronic acid-based material as a sensor that identifies carbohydrates. However, there is a lack of comprehensive study on the impact of the substituent on the pKa of monosubstituted phenylboronic acid in aqueous and non-aqueous solutions In this work, extensive exptl. data on the pKa of monosubstituted phenylboronic acid in an aqueous solution was reviewed and compared in terms of accuracy. In addition, computational, were used to predict and investigate the impact of the substituent on the pKa for a series of monosubstituted phenylboronic acid in an aqueous solution at the mol. level. Good agreement was observed between predicted and literature pKa values of monosubstituted phenylboronic acid in the aqueous solution While some deviations exist, predominantly with fluorine-containing phenylboronic acid, the COSMO-RS model is proficient at predicting the pKa of boronic acid in an aqueous solution with the accuracy of ±1.5 pKa. Subsequently, the model was used to predict the pKa of boronic acid in the non-aqueous solution, which data is not available in the literature. Furthermore, an excellent relationship is observed between the acidity of para-substituted, and to some extent, meta-substituted phenylboronic acid with the at. charge of acidic hydrogen calculated using Natural Bond Orbital (NBO) Population Anal. In contrast, the steric hindrance and the existence of other mol. forces might influence the acidity of ortho-substituted phenylboronic acid. The gathered information in this work could be of benefit for the understanding of the acidity of the boronic acid-based materials not only as a sensor but also in many diverse areas.
244205-40-1, 2-Bromophenylboronic Acid is used as an inhibitor of the hormone sensitive lipase.
2-Bromophenylboronic acid, also known as 2-Bromophenylboronic acid, is a useful research compound. Its molecular formula is C6H6BBrO2 and its molecular weight is 200.83 g/mol. The purity is usually 95%.
2-Bromophenylboronic acid is a glucose monitoring agent that has a ruthenium complex with an acidic environment. The nitro group and the amines are in close proximity to the boron center, and this proximity leads to a high nucleophilic character of the molecule. This reactivity allows 2-bromophenylboronic acid to be used as a fluorescence probe for acidic environments. 2-Bromophenylboronic acid also inhibits secretase enzymes, which are involved in Alzheimer’s disease and other neurodegenerative disorders. It is an inhibitor of γ-secretase, which is responsible for cleaving the amyloid precursor protein (APP), and it has shown efficacy against biphenyl, an anticancer drug that binds to benzodiazepine receptors. 2-Bromophenylboronic acid is also an enantiopure compound because all four substituents are different from each other., SDS of cas: 244205-40-1
