(E)-1-bromanyl-1,1,2,2-tetrakis(fluoranyl)oct-3-ene (E)-1-bromo-1,1,2,2-tetrafluoro-3-octene 74793-72-9 A838230 CAS 74793-72-9

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.

(E)-1-bromanyl-1,1,2,2-tetrakis(fluoranyl)oct-3-ene (E)-1-bromo-1,1,2,2-tetrafluoro-3-octene 74793-72-9 A838230 (CAS 74793-72-9), molecular formula C8H11BrF4 and molecular weight 263.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-1-bromanyl-1,1,2,2-tetrakis(fluoranyl)oct-3-ene (E)-1-bromo-1,1,2,2-tetrafluoro-3-octene 74793-72-9 A838230 (C8H11BrF4) 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.
