Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
8-Bromo-4-chloro-6-methylquinoline (CAS 1156602-22-0) is a high-purity analytical reference standard with the molecular formula C10H7BrClN and a molecular weight of 256.53 g/mol.
Based on its molecular formula C10H7BrClN, 8-Bromo-4-chloro-6-methylquinoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 8-Bromo-4-chloro-6-methylquinoline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
