(3,6-Difluoro-2-methoxyphenyl)boronic acid CAS 919355-30-9

Description

Compared with other compounds in its class, the molecular weight of 187.94 g/mol gives (3,6-Difluoro-2-methoxyphenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (3,6-Difluoro-2-methoxyphenyl)boronic acid (CAS 919355-30-9), a certified reference material (molecular formula C7H7BF2O3, MW 187.94 g/mol) for analytical method development and quality control.

The molecular framework of (3,6-Difluoro-2-methoxyphenyl)boronic acid (C7H7BF2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
