Description
As a certified reference material (CRM), 7-Bromo-5-chloroquinolin-8-yl thiophene-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.
7-Bromo-5-chloroquinolin-8-yl thiophene-3-carboxylate (CAS 89588-65-8) is a high-purity analytical reference standard with the molecular formula C14H7BrClNO2S and a molecular weight of 368.63 g/mol.
7-Bromo-5-chloroquinolin-8-yl thiophene-3-carboxylate (C14H7BrClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
