Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,6-Dichloro-4-(4-methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 680216-56-2) is a high-purity analytical reference standard with the molecular formula C9H8Cl2N4S and a molecular weight of 275.16 g/mol.
The molecular framework of 2,6-Dichloro-4-(4-methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)pyridine (C9H8Cl2N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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).
As a certified reference material (CRM), 2,6-Dichloro-4-(4-methyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)pyridine 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.
