Application

Hydriodic acid is a solution of hydrogen iodide in water. It is a strong acid. It is commonly used as a reagent in various reactions such as:
  • electrophilic hydriodination of alkenes and alkynes
  • cleavage of epoxides, ethers, and acetals; conversion of alcohols to iodides   
  • reducing agent for many groups including quinones, α-diketones, α-ketols, α-halo ketones, α-diazo ketones, and sulfoxides      
  • reductive cyclization of keto acids

Hydriodic acid (hypophosphorus acid as a stabilizer) can be used for the fabrication of benzylammonium hybrid layered metal-halide perovskites for spintronic and nonlinear optical applications
