Description
CATO supplies 8-Bromo-1-ethyl-2-fluoronaphthalene (CAS 2792709-80-7), a certified reference material (molecular formula C12H10BrF, MW 253.11 g/mol) for analytical method development and quality control.
The molecular framework of 8-Bromo-1-ethyl-2-fluoronaphthalene (C12H10BrF) is characterized by fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
