2-(4-Methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-3-(pyridin-2-yl)-6-(trifluoromethyl)thieno[3,2-b]pyridine CAS 672951-26-7

Description

Compared with other compounds in its class, the molecular weight of 407.44 g/mol gives 2-(4-Methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-3-(pyridin-2-yl)-6-(trifluoromethyl)thieno[3,2-b]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-Methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-3-(pyridin-2-yl)-6-(trifluoromethyl)thieno[3,2-b]pyridine (CAS 672951-26-7), molecular formula C17H12F3N5S2 and molecular weight 407.44 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 2-(4-Methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-3-(pyridin-2-yl)-6-(trifluoromethyl)thieno[3,2-b]pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
