CATO supplies 5-(1,5-Dimethyl-1h-pyrazol-3-yl)-4-methyl-4h-1,2,4-triazole-3-thiol (CAS 957299-16-0), a certified reference material (molecular formula C8H11N5S, MW 209.27 g/mol) for analytical method development and quality control.
5-(1,5-Dimethyl-1h-pyrazol-3-yl)-4-methyl-4h-1,2,4-triazole-3-thiol (C8H11N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
