1-(2-Bromoethoxy)-4-(2,2,2-trifluoroethoxy)benzene CAS 189876-55-9

Description

1-(2-Bromoethoxy)-4-(2,2,2-trifluoroethoxy)benzene (C10H10BrF3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.

1-(2-Bromoethoxy)-4-(2,2,2-trifluoroethoxy)benzene (CAS 189876-55-9), molecular formula C10H10BrF3O2 and molecular weight 299.08 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
