Shijiazhuang Sincere Chemicals Co.,Ltd

Properties Specific description Appearance Colorless or white crystalline powder, the crystals are often prismatic, and are easily deliquescent when exposed to air. Melting point 122℃ (decomposition), when heated, it first loses water molecules and then decomposes into iodine pentoxide (I₂O₅) and oxygen. Solubility - Easily soluble in water (solubility is about 2.3 g/100 mL at 20℃), and the aqueous solution is strongly acidic; - Soluble in organic solvents such as ethanol and ether. Density 3.28 g/cm³ (solid). Water absorption It has strong hygroscopicity and needs to be sealed and stored in a dry environment. Application field Chemical analysis As an oxidant for quantitative analysis, such as determining the content of metal ions such as manganese and titanium; Used for structural analysis of organic compounds (such as oxidative cleavage of sugars to determine the carbon chain structure of sugars). Organic synthesis is used to prepare compounds such as aldehydes, ketones, and carboxylic acids, such as oxidizing vicinal diols to corresponding carbonyl compounds; As an oxidant to participate in the ring-opening reaction of epoxides. Medicine and biochemistry: used as an oxidant in biological tissue staining (such as PAS staining to detect glycogen and mucopolysaccharides); some periodate derivatives have antiviral activity and are used in drug development. Other uses: as a catalyst for certain esterification reactions and polymerization reactions; intermediates for the preparation of iodate compounds.
