Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 342.42 g/mol gives 4,7-Di-p-tolyl-[1,2,5]thiadiazolo[3,4-c]pyridine-6-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4,7-Di-p-tolyl-[1,2,5]thiadiazolo[3,4-c]pyridine-6-carbonitrile (CAS 112208-66-9), a certified reference material (molecular formula C20H14N4S, MW 342.42 g/mol) for analytical method development and quality control.
The molecular framework of 4,7-Di-p-tolyl-[1,2,5]thiadiazolo[3,4-c]pyridine-6-carbonitrile (C20H14N4S) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 4,7-Di-p-tolyl-[1,2,5]thiadiazolo[3,4-c]pyridine-6-carbonitrile 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.
