Chemical Structure
Description
The occurrence of (3,4-Dichloro-5-fluorophenyl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3,4-Dichloro-5-fluorophenyl)boronic acid (CAS 1023690-35-8) is a high-purity analytical reference standard with the molecular formula C6H4BCl2FO2 and a molecular weight of 208.81 g/mol.
Structurally, (3,4-Dichloro-5-fluorophenyl)boronic acid (C6H4BCl2FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 208.81 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).
