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.
CATO supplies 5-Bromo-2-chloro-4-fluorophenol (CAS 148254-32-4), a certified reference material (molecular formula C6H3BrClFO, MW 225.44 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-2-chloro-4-fluorophenol (C6H3BrClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
