Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.33 g/mol gives 2,4-Dibromo-3,5-difluorochlorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,4-Dibromo-3,5-difluorochlorobenzene (CAS 1000577-98-9), a certified reference material (molecular formula C6HBr2ClF2, MW 306.33 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-Dibromo-3,5-difluorochlorobenzene (C6HBr2ClF2) is characterized by 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. 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.
