5-(4-pyridyl)-1<I>H</I>-1,2,4-triazole-3-thiol CAS 14910-06-6

Description

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.

5-(4-pyridyl)-1<I>H</I>-1,2,4-triazole-3-thiol (CAS 14910-06-6), molecular formula C7H16N4S and molecular weight 188.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H16N4S, 5-(4-pyridyl)-1<I>H</I>-1,2,4-triazole-3-thiol contains a nitrile group, sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 188.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
