General description

Hydriodic acid, a strong acid, is hydrogen iodide gas dissolved in water.[1]

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).[2]
It may be used in the following processes:
  • Deiodination process during the synthesis of partially fluorinated pyridinium bromides.[3]
  • As a reducing agent for oxidized graphene nanoribbons (OGN).[4]
  • In combination with red phosphorus to reduce pseudoephedrine in the synthesis of methamphetamine.[5]
