Periodic(VII) acid(Cas 10450-60-9) Usage

General Description

Periodic(VII) acid, also known as Perjodic acid, is a strong and unstable oxidizing agent with the formula H5IO6. It can be prepared by the reaction of iodine pentoxide with water, and it is one of the most powerful oxides of iodine. Periodic(VII) acid is a colorless, hygroscopic solid with strong oxidizing properties. It is commonly used as a reagent for the oxidation of various organic compounds and as a precursor to other iodine compounds. However, due to its instability, it must be handled with extreme caution, as it can decompose explosively under certain conditions.
