3-Amino-6-[(3,4-dimethoxyphenyl)methyl]-N-[(4-methoxyphenyl)methyl]-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide (CAS 939894-31-2) is a high-purity analytical reference standard with the molecular formula C26H24F3N3O4S and a molecular weight of 531.55 g/mol.
The molecular framework of 3-Amino-6-[(3,4-dimethoxyphenyl)methyl]-N-[(4-methoxyphenyl)methyl]-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide (C26H24F3N3O4S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 3-Amino-6-[(3,4-dimethoxyphenyl)methyl]-N-[(4-methoxyphenyl)methyl]-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide 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.
