Description
CATO manufactures 1,4-Dibromo-2,5-difluoro-3-(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.
1,4-Dibromo-2,5-difluoro-3-(difluoromethoxy)benzene (CAS 1806347-91-0) is a high-purity analytical reference standard with the molecular formula C7H2Br2F4O and a molecular weight of 337.89 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 1,4-Dibromo-2,5-difluoro-3-(difluoromethoxy)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
