Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Fluorophenyl)-4-((4-(methylthio)benzylidene)amino)-1H-1,2,4-triazole-5(4H)-thione.
3-(4-Fluorophenyl)-4-((4-(methylthio)benzylidene)amino)-1H-1,2,4-triazole-5(4H)-thione (CAS 764655-45-0), molecular formula C16H13FN4S2 and molecular weight 344.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(4-Fluorophenyl)-4-((4-(methylthio)benzylidene)amino)-1H-1,2,4-triazole-5(4H)-thione (C16H13FN4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 344.43 g/mol, it falls into the moderately-high-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.
As a certified reference material (CRM), 3-(4-Fluorophenyl)-4-((4-(methylthio)benzylidene)amino)-1H-1,2,4-triazole-5(4H)-thione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
