Caesium iodide can be used in Fourier Transform Infrared (FT-IR) spectrometers as a beamsplitter.
trans-Cyclooctene was first synthesized on a preparatory scale by Arthur C. Cope beginning from N,N,N-trimethylcyclooctylammonium iodide and using a Hofmann elimination.
The Nernst equation shows that hydrogen peroxide can oxidize chloride (E°= 1.36 V), bromide (E°= 1.09 V) and iodide (E°= 0.536 V) from a thermodynamic perspective under natural conditions, i.e., a temperature range of about 0-30 °C and a pH ranging from about 3 (humic soil layer) to about 8 (sea water).
Lugol's iodine, a solution of iodine in potassium iodide, named after J. G. A. Lugol.
The common and simplest approach to make vinyl iodide is addition of one equivalent HI to alkyne.
