Chemical Structure
Description
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.
2-([1,1'-Biphenyl]-4-carboxamido)-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (CAS 1216623-67-4), molecular formula C22H21N3O2SHCl and molecular weight 427.95 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-([1,1'-Biphenyl]-4-carboxamido)-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (C22H21N3O2SHCl) is characterized by a steroid core, an amide group, a sulfone group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-([1,1'-Biphenyl]-4-carboxamido)-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride 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.
