6-Methyl-2-(2-phenoxyacetamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride CAS 1216599-61-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 381.88 g/mol gives 6-Methyl-2-(2-phenoxyacetamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Methyl-2-(2-phenoxyacetamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (CAS 1216599-61-9), molecular formula C17H19N3O3SHCl and molecular weight 381.88 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Methyl-2-(2-phenoxyacetamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (C17H19N3O3SHCl) 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
