Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-(3,5-dioxo-4-phenyl-1,2,4-triazolidin-1-yl)-5-methyl-2-oxotetrahydrofuran-3-carboxylate.
Ethyl 3-(3,5-dioxo-4-phenyl-1,2,4-triazolidin-1-yl)-5-methyl-2-oxotetrahydrofuran-3-carboxylate (CAS 63376-44-3), molecular formula C16H17N3O6 and molecular weight 347.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 3-(3,5-dioxo-4-phenyl-1,2,4-triazolidin-1-yl)-5-methyl-2-oxotetrahydrofuran-3-carboxylate (C16H17N3O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 3-(3,5-dioxo-4-phenyl-1,2,4-triazolidin-1-yl)-5-methyl-2-oxotetrahydrofuran-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.
