General description

Yellow mercuric oxide shows antibacterial property and is commonly used in ophthalmic ointments.

Application

Yellow mercuric oxide in the presence of mercuric bromide catalyst may be used in the preparation of alkyl β-D-glucopyranoside tetra-O-acetates and tetra-O-benzoates from poly-O-acyl-α-D-glucopyranosyl bromides and different alcohols via Koenigs-Knorr syntheses.

Mercury electrodes preconcentrate metal chalcogenide nanoparticles effectively, enabling their detection at submicromolar concentrations (as Sigma chalcogenide) by adsorptive cathodic stripping voltammetry. Understanding the unique behavior of nanoparticle analytes during preconcentration is critical for lowering detection limits and for quantification. A
