Sodium periodate Consensus Reports
Sodium periodate Specification
The Sodium periodate is an organic compound with the formula NaIO4. The IUPAC name of this chemical is sodium periodate. With the CAS registry number 7790-28-5, it is also named as Sodium metaperiodate. The product's category is Inorganics. Besides, it is a white powder, which should be stored in a dark cool and dry place.
Physical properties about Sodium periodate are: (1)H-Bond Donor: 0; (2)H-Bond Acceptor: 4; (3)Exact Mass 213.873896; (4)MonoIsotopic Mass: 213.873896; (5)Topological Polar Surface Area: 74.3; (6)Heavy Atom Count: 6; (7)Complexity: 118; (8)Covalently-Bonded Unit Count: 2.
Preparation: this chemical can be isolated from the oxidation of sodium iodide with sodium hypochlorite and is best recrystallized from nitric acid. However, electrochemistry offers an easier alternative.
Uses of Sodium periodate: it is used to oxidize cellulose and create a biocompatible and biodegradable compound that can be used as suture, as a scaffold for 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 (ribose has vicinal diols) instead of DNA as deoxyribose does not have vicinal diols.
When you are using this chemical, please be cautious about it as the following:
It is harmful by inhalation, in contact with skin and if swallowed. It contact with combustible material may cause fire. Please keep away from combustible material. Besides, this chemical is irritating to eyes, respiratory system and skin. When you are using it, wear suitable gloves and eye/face protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
