Chemical Structure
Description
(E)-6-Ethoxy-1-methyl-2-(3-nitrostyryl)quinolin-1-ium methyl sulfate (CAS 879278-79-2), molecular formula C20H19N2O3CH3O4S and molecular weight 446.47 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-6-Ethoxy-1-methyl-2-(3-nitrostyryl)quinolin-1-ium methyl sulfate (C20H19N2O3CH3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (E)-6-Ethoxy-1-methyl-2-(3-nitrostyryl)quinolin-1-ium methyl sulfate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
