Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methyl-2-(3-phenoxybenzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride.
CATO supplies 6-Methyl-2-(3-phenoxybenzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride (CAS 1216510-96-1), a certified reference material (molecular formula C22H21N3O3SHCl, MW 443.95 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H21N3O3SHCl, 6-Methyl-2-(3-phenoxybenzamido)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxamide hydrochloride contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 443.95 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
