Description
CATO supplies 898791-68-9 (4-Bromo-2-fluorophenyl)(cyclopentyl)methanone DTXSID90642574 (CAS 898791-68-9), a certified reference material (molecular formula C12H12BrFO, MW 271.13 g/mol) for analytical method development and quality control.
898791-68-9 (4-Bromo-2-fluorophenyl)(cyclopentyl)methanone DTXSID90642574 (C12H12BrFO) contains 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; 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.
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.
