Compared with other compounds in its class, the molecular weight of 285.22 g/mol gives 4-Bromo-2,6-di-tert-butylphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-2,6-di-tert-butylphenol (CAS 1139-52-2), a certified reference material (molecular formula C14H21BrO, MW 285.22 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-2,6-di-tert-butylphenol (C14H21BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Bromo-2,6-di-tert-butylphenol 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.
