Chemical Structure
Description
The occurrence of 6-Fluoro-2,2',4,4'-tetrabromodiphenyl ether is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Fluoro-2,2',4,4'-tetrabromodiphenyl ether (CAS 876310-23-5), molecular formula C12H5Br4FO and molecular weight 503.78 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H5Br4FO, 6-Fluoro-2,2',4,4'-tetrabromodiphenyl ether contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 503.78 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 6-Fluoro-2,2',4,4'-tetrabromodiphenyl ether 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.
