Chemical Structure

[Dibromo(fluoro)methyl]benzene CAS 772339-79-4 chemical structure

Description

The occurrence of [Dibromo(fluoro)methyl]benzene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies [Dibromo(fluoro)methyl]benzene (CAS 772339-79-4), a certified reference material (molecular formula C7H5Br2F, MW 267.92 g/mol) for analytical method development and quality control.

The molecular framework of [Dibromo(fluoro)methyl]benzene (C7H5Br2F) is characterized by fluorine/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.
