CATO supplies 5-Isopropyl-1h-1,2,4-triazole-3-thiol (CAS 59689-64-4), a certified reference material (molecular formula C5H9N3S, MW 143.21 g/mol) for analytical method development and quality control.
The molecular framework of 5-Isopropyl-1h-1,2,4-triazole-3-thiol (C5H9N3S) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
