5-Bromo-1,2-difluoro-3-(2,2,2-trifluoroethoxy)benzene CAS 947534-36-3

Description

The occurrence of 5-Bromo-1,2-difluoro-3-(2,2,2-trifluoroethoxy)benzene 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.

5-Bromo-1,2-difluoro-3-(2,2,2-trifluoroethoxy)benzene (CAS 947534-36-3) is a high-purity analytical reference standard with the molecular formula C8H4BrF5O and a molecular weight of 291.01 g/mol.

Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 5-Bromo-1,2-difluoro-3-(2,2,2-trifluoroethoxy)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.01 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
