Chemical Structure
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.
CATO supplies 4-(3,5-Dimethoxyphenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazole-3-thiol (CAS 517869-97-5), a certified reference material (molecular formula C15H14N4O2S, MW 314.36 g/mol) for analytical method development and quality control.
Structurally, 4-(3,5-Dimethoxyphenyl)-5-(pyridin-4-yl)-4H-1,2,4-triazole-3-thiol (C15H14N4O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 314.36 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
