1-Bromo-3-[chloro(difluoro)-methoxy]-5-fluoro-benzene CAS 1417568-67-2 chemical structure

Description

The occurrence of 1-Bromo-3-[chloro(difluoro)-methoxy]-5-fluoro-benzene is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromo-3-[chloro(difluoro)-methoxy]-5-fluoro-benzene (CAS 1417568-67-2) is a high-purity analytical reference standard with the molecular formula C7H3BrClF3O and a molecular weight of 275.45 g/mol.

Structurally, 1-Bromo-3-[chloro(difluoro)-methoxy]-5-fluoro-benzene (C7H3BrClF3O) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 275.45 g/mol, it falls into the medium-molecular-weight range. 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), 1-Bromo-3-[chloro(difluoro)-methoxy]-5-fluoro-benzene 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.
