Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium 7-(methylthio)-3-nitro-4-oxo-4H-[1,2,4]triazolo[5,1-c][1,2,4]triazin-8-ide.
Sodium 7-(methylthio)-3-nitro-4-oxo-4H-[1,2,4]triazolo[5,1-c][1,2,4]triazin-8-ide (CAS 116061-59-7), molecular formula C5H3N6O3SNa and molecular weight 250.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Sodium 7-(methylthio)-3-nitro-4-oxo-4H-[1,2,4]triazolo[5,1-c][1,2,4]triazin-8-ide (C5H3N6O3SNa) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), Sodium 7-(methylthio)-3-nitro-4-oxo-4H-[1,2,4]triazolo[5,1-c][1,2,4]triazin-8-ide 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.
