8-Bromoinosine is used in synthetic preparation of (bromo)adenosine, (bromo)guanosine derivatives via microwave-mediated regioselective and chemoselective bromination of adenosine, inosine and guanosine derivatives. 8-Bromoinosine is also used as reagent/reactant for preparation and immunostimulating activity of purine-substituted methylglucosamines via glycosylation of purines and methylglucosamine.
