Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 496.54 g/mol gives 3-Amino-4-(4-methoxyphenyl)-N-(2-nitrophenyl)-6-phenylthieno[2,3-b]pyridine-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Amino-4-(4-methoxyphenyl)-N-(2-nitrophenyl)-6-phenylthieno[2,3-b]pyridine-2-carboxamide (CAS 332053-72-2), a certified reference material (molecular formula C27H20N4O4S, MW 496.54 g/mol) for analytical method development and quality control.
The molecular framework of 3-Amino-4-(4-methoxyphenyl)-N-(2-nitrophenyl)-6-phenylthieno[2,3-b]pyridine-2-carboxamide (C27H20N4O4S) is characterized by a steroid 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 3-Amino-4-(4-methoxyphenyl)-N-(2-nitrophenyl)-6-phenylthieno[2,3-b]pyridine-2-carboxamide 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.
