General description
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-Schiff²s Reagent (PAS) is used in histochemistry to determine carbohydrates in tissue sections.
Application
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.
