Descrição geral

Selenous acid is a dibasic acid. It is the oxoacid of selenium and can be formed by adding selenium dioxide gas to water. Selenous acid shows analogy to sulfurous acid. As a crystalline solid, the molecules are arranged in a pyramid and in a solution it behaves as a diprotic acid.

Aplicação

  • Selenic acid etching assisted vacancy engineering for designing highly active electrocatalysts toward the oxygen evolution reaction: Examination of the use of selenous acid in vacancy engineering for electrocatalysts (Zhang et al., 2021).
  • Europium (III) Catalysis for Reduction of Thionine Dye by Selenous Acid in Aqueous Sulfuric Acid Solutions: Study on the kinetics and mechanism of selenium(IV) reduction in aqueous sulfuric acid solutions (Fawzy, 2016).

1,2-Oxaselenolane Se-oxide is a novel cyclic seleninate ester that functions as a remarkably efficient glutathione peroxidase mimetic by catalyzing the reduction of tert-butyl hydroperoxide to tert-butyl alcohol in the presence of benzyl thiol. The seleninate ester can be conveniently generated

All nutritional selenium sources are transformed into the assumed common intermediate selenide for the syntheses of selenoproteins for utilization and/or of selenosugar for excretion. Methylselenol [monomethylselenide, MMSe] is the assumed intermediate leading to other methylated metabolites, dimethylselenide (DMSe) and trimethylselenonium
