Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4,5-Dipropyl-4h-1,2,4-triazole-3-thiol (CAS 667444-91-9), a certified reference material (molecular formula C8H15N3S, MW 185.29 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, 4,5-Dipropyl-4h-1,2,4-triazole-3-thiol is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
