Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system, 3,3-Difluoro-4-iodo-1,3-dihydro-2H-pyrrolo[2,3-b]pyridin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
