Iodine pentoxide Specification

The Iodine pentoxide, with the CAS registry number 12029-98-0, is also known as Diiodine pentaoxide. It belongs to the product categories of Inorganics; Halogen oxide. Its EINECS number is 234-740-2. This chemical's molecular formula is I₂O₅ and molecular weight is 333.81. What's more, its systematic name is Oxybis(iodane) tetraoxide. This iodine oxide is the anhydride of iodic acid, and the only stable anhydride of iodine. This chemical is stable at common pressure and temperature, and it should be sealed and stored in a cool and dry place. Moreover, it should be protected from reductants, organic materials, metal powder and light.

Physical properties of Iodine pentoxide are: (1)ACD/LogP: -5.67; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -5.67; (4)ACD/LogD (pH 7.4): -5.67; (5)ACD/BCF (pH 5.5): 1.00; (6)ACD/BCF (pH 7.4): 1.00 ; (7)#H bond acceptors: 5; (8)#H bond donors: 0; (9)#Freely Rotating Bonds: 2; (10)Polar Surface Area: 77.51 Å².

Preparation: this chemical is produced by dehydrating iodic acid at 200 °C in a stream of dry air.

2HIO₃ → I₂O₅ + H₂O

When you are using this chemical, please be cautious about it as the following:
This chemical can cause burns. When contact with combustible material, it may cause fire. You should keep them away from combustible material. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. When using it, you need wear suitable protective clothing, gloves and eye/face protection. You must take off immediately all contaminated clothing. In case of accident or if you feel unwell, you should seek medical advice immediately (show the label where possible).

You can still convert the following datas into molecular structure:
(1)SMILES: O=I(=O)OI(=O)=O
(2)Std. InChI: InChI=1S/I2O5/c3-1(4)7-2(5)6
