Chemical Structure
Description
The occurrence of 1-Bromo-3,4,4,4-tetrafluoro-3-(trifluoromethyl)butane is closely related to fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-3,4,4,4-tetrafluoro-3-(trifluoromethyl)butane (CAS 1274903-97-7), molecular formula C5H4BrF7 and molecular weight 276.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-3,4,4,4-tetrafluoro-3-(trifluoromethyl)butane (C5H4BrF7) 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.
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.
