Chemical Structure
Description
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.
CATO supplies 4-Bromo-3,5-bis(trifluoromethyl)aniline (CAS 268733-18-2), a certified reference material (molecular formula C8H4BrF6N, MW 308.02 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H4BrF6N, 4-Bromo-3,5-bis(trifluoromethyl)aniline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 308.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
