Description
As a certified reference material (CRM), 4-Bromo-3-(chloromethyl)phenol 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.
4-Bromo-3-(chloromethyl)phenol (CAS 1260790-72-4) is a high-purity analytical reference standard with the molecular formula C7H6BrClO and a molecular weight of 221.48 g/mol.
The molecular framework of 4-Bromo-3-(chloromethyl)phenol (C7H6BrClO) is characterized by a hydroxyl group, an ether linkage, chlorine/bromine 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 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.
