Methyl 6-(pyrazin-2-yl)thieno[3,2-b]pyridine-3-carboxylate CAS 959245-23-9

Description

The occurrence of Methyl 6-(pyrazin-2-yl)thieno[3,2-b]pyridine-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 6-(pyrazin-2-yl)thieno[3,2-b]pyridine-3-carboxylate (CAS 959245-23-9) is a high-purity analytical reference standard with the molecular formula C13H9N3O2S and a molecular weight of 271.29 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 6-(pyrazin-2-yl)thieno[3,2-b]pyridine-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
