Chemical Structure
Description
As a certified reference material (CRM), 2,6-Diamino-4-(o-tolyl)-4H-thiopyran-3,5-dicarbonitrile 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.
2,6-Diamino-4-(o-tolyl)-4H-thiopyran-3,5-dicarbonitrile (CAS 202405-84-3) is a high-purity analytical reference standard with the molecular formula C14H12N4S and a molecular weight of 268.34 g/mol.
The molecular framework of 2,6-Diamino-4-(o-tolyl)-4H-thiopyran-3,5-dicarbonitrile (C14H12N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
