Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-bromo-7-chloro-8-methylquinoline-3-carboxylate.
Ethyl 4-bromo-7-chloro-8-methylquinoline-3-carboxylate (CAS 1242260-84-9) is a high-purity analytical reference standard with the molecular formula C13H11BrClNO2 and a molecular weight of 328.59 g/mol.
Based on its molecular formula C13H11BrClNO2, Ethyl 4-bromo-7-chloro-8-methylquinoline-3-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 328.59 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 4-bromo-7-chloro-8-methylquinoline-3-carboxylate 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.
