Description
Compared with other compounds in its class, the molecular weight of 385.44 g/mol gives Ethyl 3-({[(benzyloxy)imino]methyl}amino)-4-methoxythieno[2,3-b]pyridine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 3-({[(benzyloxy)imino]methyl}amino)-4-methoxythieno[2,3-b]pyridine-2-carboxylate (CAS 341966-63-0), molecular formula C19H19N3O4S and molecular weight 385.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 3-({[(benzyloxy)imino]methyl}amino)-4-methoxythieno[2,3-b]pyridine-2-carboxylate (C19H19N3O4S) 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 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Ethyl 3-({[(benzyloxy)imino]methyl}amino)-4-methoxythieno[2,3-b]pyridine-2-carboxylate 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.
