(2-Chloro-4-fluoro-5-(methoxycarbonyl)phenyl)boronic acid CAS 957066-03-4

Description

The occurrence of (2-Chloro-4-fluoro-5-(methoxycarbonyl)phenyl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2-Chloro-4-fluoro-5-(methoxycarbonyl)phenyl)boronic acid (CAS 957066-03-4), a certified reference material (molecular formula C8H7BClFO4, MW 232.40 g/mol) for analytical method development and quality control.

The molecular framework of (2-Chloro-4-fluoro-5-(methoxycarbonyl)phenyl)boronic acid (C8H7BClFO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
