Chemical Structure
Description
CATO supplies 3-(Dimethylamino)-N,4-diphenyl-1H-pyrazole-1-carbothioamide (CAS 321538-53-8), a certified reference material (molecular formula C18H18N4S, MW 322.43 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Dimethylamino)-N,4-diphenyl-1H-pyrazole-1-carbothioamide (C18H18N4S) 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.
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), 3-(Dimethylamino)-N,4-diphenyl-1H-pyrazole-1-carbothioamide 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.
