Quality Control of Pyridin-3-ylboronic acid And the article was included in Electroanalysis in 2020. The article conveys some information:
In this study, we found that glucose enhance electrochemiluminescence (ECL) intensity of both Au nanoclusters (Au NCs) and carbon quantum dots (CQDs) with K2S2O8 as the co-reactants. The enhancing effects by Au NCs and CQDs were overlapped, enabling the detection of glucose. The increased ECL intensity of glucose was linear with the logarithm of concentrations of glucose in the range of 50μM-3.0 mM, and the limit of detection is 20μM. Anti-interruption ability was achieved, and ascorbic acid, urea, and uric acid had little influence to glucose detection. This method realized the direct detection of glucose by enhancing ECL of Au NCs and CQDs, which was fast and economic, possessing potential applications for glucose detection in human serum. After reading the article, we found that the author used Pyridin-3-ylboronic acid(cas: 1692-25-7Quality Control of Pyridin-3-ylboronic acid)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Quality Control of Pyridin-3-ylboronic acid
