Description
CATO manufactures 1-Bromo-4-difluoromethoxy-2-fluorobenzene, 97% 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.
CATO supplies 1-Bromo-4-difluoromethoxy-2-fluorobenzene, 97% (CAS 1242258-38-3), a certified reference material (molecular formula C7H4BrF3O, MW 241.01 g/mol) for analytical method development and quality control.
1-Bromo-4-difluoromethoxy-2-fluorobenzene, 97% (C7H4BrF3O) contains a hydroxyl group, an ether linkage, fluorine/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.
