General description
Iodine monobromide is an interhalogen compound used as an electrophile in the synthesis of polyketide structural units.
Iodine monobromide (IBr) is a powerful iodinating agent employed in organic synthesis. IBr is commonly used in cleavage of carbon–metal bonds, electrophilic addition to alkenes, α-bromination of steroidal ketones and aldehydes, and in diastereoselective cyclizations of homoallylic carbonates.

[Structure: see text] A strategically novel approach to the formation of syn-1,3-diol mono- and diethers through electrophilic activation of homoallylic alkoxymethyl ethers has been developed. The resulting polyketide-like synthetic fragments are generated in good yield and with excellent stereocontrol. A

The studies of 116 females with chronic nonspecific salpingo-oophoritis demonstrate that combination of low-frequency magnetic field with iodine-bromine water effectively corrects immunological indices, i.e. improves T- and B-cell immunity, production of IgM and IgA, proportion of immunoregulatory subpopulations of T-lymphocytes.

The iodine value (iodine number) is an important analytical characteristic of fats and oils. Leading pharmacopeias determine it using iodine monobromide (Hanus method). We used methyl oleate as a simple analog of unsaturated triacylglycerols to identify the products. After performing
