Description
Ethyl 3-carbamoyl-2-(5-nitrothiophene-2-carboxamido)-4,7-dihydrothieno[2,3-c]pyridine-6(5H)-carboxylate (CAS 864925-73-5), molecular formula C16H16N4O6S2 and molecular weight 424.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 3-carbamoyl-2-(5-nitrothiophene-2-carboxamido)-4,7-dihydrothieno[2,3-c]pyridine-6(5H)-carboxylate (C16H16N4O6S2) is characterized by a flavonoid core, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
