Chemical Structure
Description
1-(4-Bromophenyl)-2,2,2-trifluoroethanol (C8H6BrF3O) 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.
1-(4-Bromophenyl)-2,2,2-trifluoroethanol (CAS 76911-73-4), molecular formula C8H6BrF3O and molecular weight 255.03 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.
