2-Fluoro-5-(methylthio)phenylboronic acid CAS 2121512-51-2

Description

Compared with other compounds in its class, the molecular weight of 186.01 g/mol gives 2-Fluoro-5-(methylthio)phenylboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Fluoro-5-(methylthio)phenylboronic acid (CAS 2121512-51-2), molecular formula C7H8BFO2S and molecular weight 186.01 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Fluoro-5-(methylthio)phenylboronic acid (C7H8BFO2S) is characterized by a sulfone group, 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).

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.

As a certified reference material (CRM), 2-Fluoro-5-(methylthio)phenylboronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
