Description

Compared with other compounds in its class, the molecular weight of 257.02 g/mol gives 2-Fluoro-4-(trifluoromethyl)benzyl bromide 239087-07-1 A22328 a-Bromo-2-fluoro-4-(trifluoromethyl)toluene;a-bromo-2-fluoro-4-(trifluoromethyl)toluene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Fluoro-4-(trifluoromethyl)benzyl bromide 239087-07-1 A22328 a-Bromo-2-fluoro-4-(trifluoromethyl)toluene;a-bromo-2-fluoro-4-(trifluoromethyl)toluene (CAS 239087-07-1), a certified reference material (molecular formula C8H5BrF4, MW 257.02 g/mol) for analytical method development and quality control.

2-Fluoro-4-(trifluoromethyl)benzyl bromide 239087-07-1 A22328 a-Bromo-2-fluoro-4-(trifluoromethyl)toluene;a-bromo-2-fluoro-4-(trifluoromethyl)toluene (C8H5BrF4) contains fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
