Description
Compared with other compounds in its class, the molecular weight of 320.73 g/mol gives Ethyl 2-(2-carbamoyl-4-chlorophenoxy)nicotinate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-(2-carbamoyl-4-chlorophenoxy)nicotinate (CAS 1160264-40-3), molecular formula C15H13ClN2O4 and molecular weight 320.73 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-(2-carbamoyl-4-chlorophenoxy)nicotinate (C15H13ClN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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 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.
As a certified reference material (CRM), Ethyl 2-(2-carbamoyl-4-chlorophenoxy)nicotinate 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.
