Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, 4-methyl-5-(piperidin-4-yl)-4H-1,2,4-triazole-3-thiol hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.75 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.
4-methyl-5-(piperidin-4-yl)-4H-1,2,4-triazole-3-thiol hydrochloride (CAS 1158193-23-7), molecular formula C8H14N4SHCl and molecular weight 234.75 g/mol, is a CATO reference standard with documented purity and traceability.
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.
