Chemical Structure
Description
The occurrence of 3-Amino-N-(2-chlorophenethyl)-6-(pyridin-4-yl)thieno[2,3-b]pyridine-2-carboxamide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Amino-N-(2-chlorophenethyl)-6-(pyridin-4-yl)thieno[2,3-b]pyridine-2-carboxamide (CAS 496019-25-1), a certified reference material (molecular formula C21H17ClN4OS, MW 408.90 g/mol) for analytical method development and quality control.
The molecular framework of 3-Amino-N-(2-chlorophenethyl)-6-(pyridin-4-yl)thieno[2,3-b]pyridine-2-carboxamide (C21H17ClN4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine 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. 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), 3-Amino-N-(2-chlorophenethyl)-6-(pyridin-4-yl)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.
