Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
ethyl 4-(acetyloxy)-2-(ethylsulfanyl)-6,7-difluoroquinoline-3-carboxylate (CAS 154330-68-4) is a high-purity analytical reference standard with the molecular formula C16H25F2NO4S and a molecular weight of 365.44 g/mol.
ethyl 4-(acetyloxy)-2-(ethylsulfanyl)-6,7-difluoroquinoline-3-carboxylate (C16H25F2NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), ethyl 4-(acetyloxy)-2-(ethylsulfanyl)-6,7-difluoroquinoline-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.
