Chemical Structure
Description
Structurally, 689254-23-7 Benzene, 1-(bromomethyl)-2,3-difluoro-4-methoxy- CTK1H5703 (C8H7BrF2O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 237.04 g/mol, it falls into the medium-molecular-weight range. 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).
