Chemical Structure
Description
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.
1-(4-Bromo-2-methylphenyl)ethan-1-amine hydrochloride (CAS 2918779-86-7), molecular formula C9H12BrNHCl and molecular weight 250.56 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine/bromine substitution, 1-(4-Bromo-2-methylphenyl)ethan-1-amine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
