The occurrence of 4-Bromo-2,3,5,6-tetrafluoro-N-methylaniline is closely related to a nitrile group, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Bromo-2,3,5,6-tetrafluoro-N-methylaniline (CAS 1233506-07-4), a certified reference material (molecular formula C7H4BrF4N, MW 258.01 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, 4-Bromo-2,3,5,6-tetrafluoro-N-methylaniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
