- Sodium periodate
Sodium periodate can refer to two different chemical compounds which are essentially sodium salts of the two varieties of periodate ion. Sodium metaperiodate (often abbreviated as m-periodate) has the formula NaIO4. Sodium orthoperiodate (often abbreviated as o-periodate) has the formula Na5IO6. Both salts are useful in certain synthetic chemistries for the oxidative power of the periodate ion.
Density is 3,865 kg m-3. It is soluble in water. When heated, it decomposes to form sodium iodate (NaIO3) and oxygen. This
decompositionreaction is catalyzed by the presence of manganese(IV) oxide.
Sodium periodate is used to oxidize
celluloseand create a biocompatibleand biodegradable compoundthat can be used as suture, as a scaffoldfor tissue engineering, or for drug delivery.
Sodium periodate can be used in solution to open saccharide rings between vicinal diols leaving two aldehyde groups. This process is often used in labeling saccharides with fluorescent molecules or other tags such as
biotin. Because the process requires vicinal diols, periodate oxidation is often used to selectively label RNA( ribosehas vicinal diols) instead of DNAas deoxyribosedoes not have vicinal diols.
