CATO supplies 5-((5-Methyl-1h-pyrazol-1-yl)methyl)-4-((tetrahydrofuran-2-yl)methyl)-4h-1,2,4-triazole-3-thiol (CAS 1005651-99-9), a certified reference material (molecular formula C12H17N5OS, MW 279.36 g/mol) for analytical method development and quality control.
Structurally, 5-((5-Methyl-1h-pyrazol-1-yl)methyl)-4-((tetrahydrofuran-2-yl)methyl)-4h-1,2,4-triazole-3-thiol (C12H17N5OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 279.36 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
