Chemical Structure
Description
The occurrence of 3-Amino-6-(pyridin-3-yl)thieno[2,3-b]pyridine-2-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Amino-6-(pyridin-3-yl)thieno[2,3-b]pyridine-2-carbonitrile (CAS 118947-66-3), a certified reference material (molecular formula C13H8N4S, MW 252.29 g/mol) for analytical method development and quality control.
The molecular framework of 3-Amino-6-(pyridin-3-yl)thieno[2,3-b]pyridine-2-carbonitrile (C13H8N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
