General description

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.
Hydriodic acid is hydrogen iodide gas dissolved in water. It is a strong acid generally used as a reducing agent.

Application

Hydriodic acid may be used in the synthesis of trideuterio-[13C]-methyl iodide and [13C]-methyl iodide.
