Description
As a certified reference material (CRM), 3-(Benzylthio)-5H-[1,2,4]triazino[5,6-b]indole 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.
3-(Benzylthio)-5H-[1,2,4]triazino[5,6-b]indole (CAS 73718-26-0), molecular formula C16H12N4S and molecular weight 292.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(Benzylthio)-5H-[1,2,4]triazino[5,6-b]indole (C16H12N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 292.36 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.
