| 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 |
