3-Amino-2-benzoyl-6-oxo-6H,7H-thieno[2,3-b]pyridine-5-carboxylic acid CAS 439946-22-2

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.

3-Amino-2-benzoyl-6-oxo-6H,7H-thieno[2,3-b]pyridine-5-carboxylic acid (CAS 439946-22-2) is a high-purity analytical reference standard with the molecular formula C15H14N2O4S and a molecular weight of 318.35 g/mol.

The molecular framework of 3-Amino-2-benzoyl-6-oxo-6H,7H-thieno[2,3-b]pyridine-5-carboxylic acid (C15H14N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, 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.
