Chemical Structure
Description
Based on its molecular formula C11H6BrClF3N, 3-Bromo-4-chloro-2-methyl-6-(trifluoromethyl)quinoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 324.52 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.
3-Bromo-4-chloro-2-methyl-6-(trifluoromethyl)quinoline (CAS 1333253-38-5), molecular formula C11H6BrClF3N and molecular weight 324.52 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
