一般描述
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.
应用
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.
