5-Bromo-1-(2,2-difluoroethoxy)-2,3-difluorobenzene CAS 947534-37-4 chemical structure

Description

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.

5-Bromo-1-(2,2-difluoroethoxy)-2,3-difluorobenzene (CAS 947534-37-4), molecular formula C8H5BrF4O and molecular weight 273.02 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 5-Bromo-1-(2,2-difluoroethoxy)-2,3-difluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.02 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).

CATO manufactures 5-Bromo-1-(2,2-difluoroethoxy)-2,3-difluorobenzene 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.
