Description and Uses
Sodium periodate is an inorganic salt, composed of a sodium cation and the periodate anion. It may also be regarded as the sodium salt of periodic acid. Like many periodates it can exist in two different forms: sodium metaperiodate, which has the formula NaIO4, and sodium orthoperiodate, normally this means sodium hydrogen periodate (Na2H3IO6) but the fully reacted sodium orthoperiodate salt, Na5IO6, can also be prepared. Both salts are useful oxidising agents.
Sodium metaperiodate is used as an oxidizing reagent involved in the oxidation of cellulose. It is involved in the cleavage of vicinal diols to prepare two aldehydes. This oxidation is commonly used in selectively label RNA, saccharides and other compounds with vicinal diols.
