Chemical Structure
Description
The occurrence of 5-Bromo-1,3-dichloro-2-(difluoromethoxy)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 5-Bromo-1,3-dichloro-2-(difluoromethoxy)benzene (CAS 929621-36-3), a certified reference material (molecular formula C7H3BrCl2F2O, MW 291.90 g/mol) for analytical method development and quality control.
5-Bromo-1,3-dichloro-2-(difluoromethoxy)benzene (C7H3BrCl2F2O) 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.
CATO manufactures 5-Bromo-1,3-dichloro-2-(difluoromethoxy)benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
