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.
6-Bromo-2-chloro-4-methylquinoline (CAS 3913-19-7) is a high-purity analytical reference standard with the molecular formula C10H7BrClN and a molecular weight of 256.53 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution, 6-Bromo-2-chloro-4-methylquinoline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.53 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.
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.
