What is a Periodic acid (HIO₄)?

Periodic acid (HIO₄) is a strong oxidizing agent that is known for its ability to oxidize various substances. It typically appears as colorless or pale yellow crystals. This compound contains iodine in a high oxidation state, giving it potent oxidative properties, making it essential in both organic synthesis and analytical chemistry. Periodic acid is widely used in organic chemistry, particularly for oxidizing functional groups like alcohols and epoxides. It plays a crucial role in the synthesis of iodine-containing compounds, including iodine esters and other iodine-based substances.

As an oxidizing agent, periodic acid is also used in redox reactions to facilitate chemical transformations. Its strong oxidative nature makes it valuable in numerous chemical processes. Due to its high reactivity, periodic acid should be handled with care. Proper protective equipment is necessary to avoid exposure, as it can irritate the skin and eyes.
