Chemical Structure

4-Bromo-2,3-dimethylphenol CAS 22802-37-5 chemical structure

Description

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.

4-Bromo-2,3-dimethylphenol (CAS 22802-37-5) is a high-purity analytical reference standard with the molecular formula C8H9BrO and a molecular weight of 201.06 g/mol.

The molecular framework of 4-Bromo-2,3-dimethylphenol (C8H9BrO) 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 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).

As a certified reference material (CRM), 4-Bromo-2,3-dimethylphenol 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.
