Compared with other compounds in its class, the molecular weight of 218.28 g/mol gives 4-Cyclopropyl-5-(pyridin-4-yl)-4h-1,2,4-triazole-3-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Cyclopropyl-5-(pyridin-4-yl)-4h-1,2,4-triazole-3-thiol (CAS 854137-75-0), a certified reference material (molecular formula C10H10N4S, MW 218.28 g/mol) for analytical method development and quality control.
Structurally, 4-Cyclopropyl-5-(pyridin-4-yl)-4h-1,2,4-triazole-3-thiol (C10H10N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 218.28 g/mol, it falls into the medium-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.
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.
