Chemical Structure
Description
The molecular framework of 4-Amino-5-(3-methyl-1h-pyrazol-5-yl)-4h-1,2,4-triazole-3-thiol (C6H8N6S) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-Amino-5-(3-methyl-1h-pyrazol-5-yl)-4h-1,2,4-triazole-3-thiol (CAS 40535-09-9), molecular formula C6H8N6S and molecular weight 196.23 g/mol, is a CATO reference standard with documented purity and traceability.
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), 4-Amino-5-(3-methyl-1h-pyrazol-5-yl)-4h-1,2,4-triazole-3-thiol 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.
