Chemical Structure
Description
2-Bromo-1-chloro-4-[chloro(difluoro)methoxy]benzene (CAS 1417567-65-7), molecular formula C7H3BrCl2F2O and molecular weight 291.90 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system, 2-Bromo-1-chloro-4-[chloro(difluoro)methoxy]benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Bromo-1-chloro-4-[chloro(difluoro)methoxy]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.
