Chemical Structure
Description
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.
1-Bromo-3-(1,1,2,2,2-pentafluoroethoxy)benzene stabilized over potassium carbonate (CAS 59935-56-7) is a high-purity analytical reference standard with the molecular formula C8H4BrF5O and a molecular weight of 291.01 g/mol.
1-Bromo-3-(1,1,2,2,2-pentafluoroethoxy)benzene stabilized over potassium carbonate (C8H4BrF5O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
