Chemical Structure
Description
The occurrence of (2,5-Dichloro-3-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.
(2,5-Dichloro-3-fluorophenyl)boronic acid (CAS 2121511-41-7) is a high-purity analytical reference standard with the molecular formula C6H4BCl2FO2 and a molecular weight of 208.81 g/mol.
Structurally, (2,5-Dichloro-3-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
