Chemical Structure

1-Bromo-4-[chloro(difluoro)-methoxy]-2-fluoro-benzene CAS 1417569-65-3 chemical structure

Description

The occurrence of 1-Bromo-4-[chloro(difluoro)-methoxy]-2-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.

CATO supplies 1-Bromo-4-[chloro(difluoro)-methoxy]-2-fluoro-benzene (CAS 1417569-65-3), a certified reference material (molecular formula C7H3BrClF3O, MW 275.45 g/mol) for analytical method development and quality control.

1-Bromo-4-[chloro(difluoro)-methoxy]-2-fluoro-benzene (C7H3BrClF3O) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-4-[chloro(difluoro)-methoxy]-2-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.
