Chemical Structure
Description
The occurrence of (2,4-Dichloro-3-formylphenyl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2,4-Dichloro-3-formylphenyl)boronic acid (CAS 480438-53-7), molecular formula C7H5BCl2O3 and molecular weight 218.83 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2,4-Dichloro-3-formylphenyl)boronic acid (C7H5BCl2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
