6,7-Dihydro-2H-pyrrolo[2,1-c][1,2,4]triazole-3(5H)-thione (CAS 539804-69-8) is a high-purity analytical reference standard with the molecular formula C5H7N3S and a molecular weight of 141.19 g/mol.
The molecular framework of 6,7-Dihydro-2H-pyrrolo[2,1-c][1,2,4]triazole-3(5H)-thione (C5H7N3S) 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.
