Description

General description

Hydriodic acid, a strong acid, is hydrogen iodide gas dissolved in water.

Application

Hydriodic acid was used for derivatization of urine samples by iodination to detect aromatic amines using multi-dimensional gas chromatography mass spectrometry (GCxGC-qMS).
It may be used in the following processes:

• Deiodination process during the synthesis of partially fluorinated pyridinium bromides.
• As a reducing agent for oxidized graphene nanoribbons (OGN).
• In combination with red phosphorus to reduce pseudoephedrine in the synthesis of methamphetamine.
