General description

Electrochemical oxidation of 2,3-dihydroxybenzaldehyde in methanol at various pH has been studied using cyclic voltammetry and controlled-potential coulometry.

Application

2,3-Dihydroxybenzaldehyde was used in the synthesis of copper(II) complexes of Schiff bases. It was also used in the synthesis of 2-ethoxy-3-hydroxy-4-nitrobenzoic acid.

In the present work, a graphene encapsulated ZnO/Co3O4 (GE/ZnO/Co3O4) core-shell hybrid is fabricated through a facile self-assembly approach, where the mutual electrostatic interaction force drives the ZnO/Co3O4 heteronanostructures to be fully wrapped with flexible ultrathin graphene shells. The as-prepared GE/ZnO/Co3O4

Activities of conventional antifungal agents, fludioxonil, strobilurin and antimycin A, which target the oxidative and osmotic stress response systems, were elevated by coapplication of certain benzo analogs (aldehydes and acids). Fungal tolerance to 2,3-dihydroxybenzaldehyde or 2,3-dihydroxybenzoic acid was found to
