4-Methyl-5-(3-(thiophen-2-yl)-6-(trifluoromethyl)thieno[3,2-b]pyridin-2-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione CAS 477854-06-1

Description

Structurally, 4-Methyl-5-(3-(thiophen-2-yl)-6-(trifluoromethyl)thieno[3,2-b]pyridin-2-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (C15H9F3N4S3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 398.45 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4-Methyl-5-(3-(thiophen-2-yl)-6-(trifluoromethyl)thieno[3,2-b]pyridin-2-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 477854-06-1) is a high-purity analytical reference standard with the molecular formula C15H9F3N4S3 and a molecular weight of 398.45 g/mol.

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.
