(2,4-Dichloro-6-ethylphenyl)boronic acid CAS 1234009-21-2

Description

The occurrence of (2,4-Dichloro-6-ethylphenyl)boronic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2,4-Dichloro-6-ethylphenyl)boronic acid (CAS 1234009-21-2), a certified reference material (molecular formula C8H9BCl2O2, MW 218.87 g/mol) for analytical method development and quality control.

The molecular framework of (2,4-Dichloro-6-ethylphenyl)boronic acid (C8H9BCl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
