Descrição geral

Periodic acid is an inorganic acid commonly used as an oxidizing agent. Periodic acid oxidation is one of the steps in the periodate-resorcinol assay, used in the determination of sialic acid. Periodic acid reacts with 1,2 glycol linkage of carbohydrates to form aldehydes which can be stained by Schiff′s reagent. Therefore periodic-acid-Schiff′s reagent (PAS) is used in histochemistry to determine carbohydrates in tissue sections.

Aplicação

Periodic acid may be used in the following reactions:
  • Oxidation of alcohols to ketones and aldehydes.
  • Oxidation hydroxylamine derivatives.
  • Oxidation of arenes to quinones.
  • Deprotection of the dithio- and oxathio-derivatives.
  • Oxidative degradation of epoxidized natural rubber (ENR).
  • Oxidation of urazoles and bis-urazoles to triazolinediones.
  • Oxidative cleavage of glucosazone.
