Product Overview

Potassium Metaperiodate 99% Extra Pure (CAS No. 7790-21-8) is the potassium salt of metaperiodic acid and contains iodine in the +7 oxidation state. Periodate is a selective high-valent oxidant particularly recognised for oxidative cleavage of substrates containing suitably arranged neighbouring oxygen-bearing groups, including vicinal diols. This reactivity provides access to carbonyl-containing products and makes periodate useful in organic, carbohydrate and materials chemistry.

The Extra Pure grade is intended for preparative oxidation, functional-group transformation and research work requiring a defined periodate source.

Typical Applications

• Oxidative cleavage of vicinal diols in preparative organic chemistry.
• Periodate oxidation of carbohydrate and polyol structures.
• Generation of aldehyde functionality from suitable diol-containing substrates.
• Oxidative modification of polysaccharides and related materials.
• Preparation of periodate-containing oxidation systems.
• Research into iodine(VII) redox and selective oxidation chemistry.

Common Synonyms

• Potassium periodate
• Potassium metaperiodate
• Potassium periodate(VII)
• Periodic acid potassium salt
• Potassium tetraoxidoiodate(VII)

Storage Conditions

Store tightly closed, dry and protected from contamination by reducing or readily oxidisable substances. Preserve oxidising activity by avoiding introduction of organic residues or other contaminants that could consume periodate during storage.
