General description

Hydriodic acid is hydrogen iodide gas dissolved in water. It is a strong acid generally used as a reducing agent.
Hydriodic acid (HI) along with red phosphorus (HI/red P) plays the role of a reducing agent for the preparation of methamphetamine. HI/Phosphorous causes the reduction of various polycyclic quinones. HI also participates as a reducing agent for the conversion of various polyarene quinones, hydroquinones and phenols to the corresponding aromatic hydrocarbons.

Application

Hydriodic acid may be used as a reagent for the conversion of fatty alcohols and glyceryl ethers to alkyl iodides.
