Chemical Structure
Description
The occurrence of 2-Bromo-2-fluoro-1-phenylethan-1-one is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-2-fluoro-1-phenylethan-1-one (CAS 321-75-5) is a high-purity analytical reference standard with the molecular formula C8H6BrFO and a molecular weight of 217.04 g/mol.
Structurally, 2-Bromo-2-fluoro-1-phenylethan-1-one (C8H6BrFO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 217.04 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).
