Chemical Structure
Description
The occurrence of 2,4-Dibromo-5-methylbenzotrifluoride 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 2,4-Dibromo-5-methylbenzotrifluoride (CAS 231285-88-4), a certified reference material (molecular formula C8H5Br2F3, MW 317.93 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-Dibromo-5-methylbenzotrifluoride (C8H5Br2F3) 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. 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.
