4-Bromo-2-ethylphenylboronic acid CAS 1046861-62-4

Description

Compared with other compounds in its class, the molecular weight of 228.88 g/mol gives 4-Bromo-2-ethylphenylboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromo-2-ethylphenylboronic acid (CAS 1046861-62-4) is a high-purity analytical reference standard with the molecular formula C8H10BBrO2 and a molecular weight of 228.88 g/mol.

The molecular framework of 4-Bromo-2-ethylphenylboronic acid (C8H10BBrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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.

CATO manufactures 4-Bromo-2-ethylphenylboronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
