Chemical Structure
Description
The occurrence of 1,4-Dibromoperfluorobutane is closely related to fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,4-Dibromoperfluorobutane (CAS 335-48-8), a certified reference material (molecular formula C4Br2F8, MW 359.84 g/mol) for analytical method development and quality control.
The molecular framework of 1,4-Dibromoperfluorobutane (C4Br2F8) 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.
As a certified reference material (CRM), 1,4-Dibromoperfluorobutane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
