Chemical Structure
Description
2-(Methylthio)-1,5-diphenyl-1H-[1,2,4]triazolo[1,5-c]quinazolin-4-ium iodide (CAS 62495-57-2) is a high-purity analytical reference standard with the molecular formula C22H17N4SI and a molecular weight of 496.37 g/mol.
The molecular framework of 2-(Methylthio)-1,5-diphenyl-1H-[1,2,4]triazolo[1,5-c]quinazolin-4-ium iodide (C22H17N4SI) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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), 2-(Methylthio)-1,5-diphenyl-1H-[1,2,4]triazolo[1,5-c]quinazolin-4-ium iodide 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.
