Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.91 g/mol gives 3-Bromo-4,5-dichloroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Bromo-4,5-dichloroaniline (CAS 36406-91-4), a certified reference material (molecular formula C6H4BrCl2N, MW 240.91 g/mol) for analytical method development and quality control.
3-Bromo-4,5-dichloroaniline (C6H4BrCl2N) contains a nitrile group, chlorine/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.
