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.
