Hydroiodic Acid 55% to 57% CAS # : 10034-85-2

Hydrogen iodide (HI) is a diatomic molecule. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid. Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions; whereas, the other is an aqueous solution of said gas. They are interconvertible. HI is used in organic and inorganic synthesis as one of the primary sources of iodine and as a reducing agent.

Use of Hydroiodic Acid :

Hydroiodic acid is currently listed as a Federal DEA List I Chemical.

Owing to its usefulness as a reducing agent, reduction with HI and red phosphorus has become the most popular method to produce methamphetamine.

Clandestine chemists react pseudoephedrine (recovered from antihistamine pills) with hydroiodic acid and red phosphorus under heat, HI reacts with pseudoephedrine to form iodoephedrine, an intermediate which is reduced primarily to methamphetamine.

This reaction is stereoselective, producing (d)-methamphetamine.

Lab using the HI/P method:

Due to its listed status and closely monitored sales, clandestine chemists now use red phosphorus and iodine to generate hydroiodic acid in situ.
