344-04-7 S88219080S Bromopentafluorobenzene Benzene, 1-bromo-2,3,4,5,6-pentafluoro- Benzene, bromopentafluoro- Bromoperfluorobenzene EINECS 206-449-0 NSC 21630 Pentafluorobromobenzene Pentafluorophenyl bromide UNII-S88219080S CAS 344-04-7 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 344-04-7 S88219080S Bromopentafluorobenzene Benzene, 1-bromo-2,3,4,5,6-pentafluoro- Benzene, bromopentafluoro- Bromoperfluorobenzene EINECS 206-449-0 NSC 21630 Pentafluorobromobenzene Pentafluorophenyl bromide UNII-S88219080S (CAS 344-04-7), a certified reference material (molecular formula C6H6BrF5, MW 253.01 g/mol) for analytical method development and quality control.

The molecular framework of 344-04-7 S88219080S Bromopentafluorobenzene Benzene, 1-bromo-2,3,4,5,6-pentafluoro- Benzene, bromopentafluoro- Bromoperfluorobenzene EINECS 206-449-0 NSC 21630 Pentafluorobromobenzene Pentafluorophenyl bromide UNII-S88219080S (C6H6BrF5) is characterized by fluorine/bromine substitution. 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. 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.
