3,5-Difluoro-2-methoxybenzeneboronic acid CAS 737000-76-9

Description

Compared with other compounds in its class, the molecular weight of 187.94 g/mol gives 3,5-Difluoro-2-methoxybenzeneboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5-Difluoro-2-methoxybenzeneboronic acid (CAS 737000-76-9) is a high-purity analytical reference standard with the molecular formula C7H7BF2O3 and a molecular weight of 187.94 g/mol.

3,5-Difluoro-2-methoxybenzeneboronic acid (C7H7BF2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
