1-Bromo-2,3-dichloro-4-methoxybenzene CAS 109803-52-3

Description

The occurrence of 1-Bromo-2,3-dichloro-4-methoxybenzene is closely related to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromo-2,3-dichloro-4-methoxybenzene (CAS 109803-52-3) is a high-purity analytical reference standard with the molecular formula C7H5BrCl2O and a molecular weight of 255.92 g/mol.

The molecular framework of 1-Bromo-2,3-dichloro-4-methoxybenzene (C7H5BrCl2O) 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. 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.

As a certified reference material (CRM), 1-Bromo-2,3-dichloro-4-methoxybenzene 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.
