Chemical Structure

Methylfluorophenyl Boronic Acid Impurity Certified Reference Standard CAS 139911-29-8 chemical structure

Description

The molecular framework of Methylfluorophenyl Boronic Acid Impurity Certified Reference Standard (C7H8BFO2) 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. 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).

CATO supplies Methylfluorophenyl Boronic Acid Impurity Certified Reference Standard (CAS 139911-29-8), a certified reference material (molecular formula C7H8BFO2, MW 153.95 g/mol) for analytical method development and quality control.

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.
