Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-6-methyl-N-phenyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydrothieno[2,3-b][1,6]naphthyridine-2-carboxamide.
CATO supplies 3-Amino-6-methyl-N-phenyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydrothieno[2,3-b][1,6]naphthyridine-2-carboxamide (CAS 340817-27-8), a certified reference material (molecular formula C22H20N4OS2, MW 420.55 g/mol) for analytical method development and quality control.
The molecular framework of 3-Amino-6-methyl-N-phenyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydrothieno[2,3-b][1,6]naphthyridine-2-carboxamide (C22H20N4OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-6-methyl-N-phenyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydrothieno[2,3-b][1,6]naphthyridine-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.
