2-Bromo-3-chloro-1-fluoro-4-methoxybenzene CAS 1785613-56-0

Description

Compared with other compounds in its class, the molecular weight of 239.47 g/mol gives 2-Bromo-3-chloro-1-fluoro-4-methoxybenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromo-3-chloro-1-fluoro-4-methoxybenzene (CAS 1785613-56-0), molecular formula C7H5BrClFO and molecular weight 239.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Bromo-3-chloro-1-fluoro-4-methoxybenzene (C7H5BrClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/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 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).

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), 2-Bromo-3-chloro-1-fluoro-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.
