Description
CATO supplies Diethyl 1-(4-(methylthio)phenyl)-5-phenyl-1H-pyrazole-3,4-dicarboxylate (CAS 96722-83-7), a certified reference material (molecular formula C22H22N2O4S, MW 410.49 g/mol) for analytical method development and quality control.
The molecular framework of Diethyl 1-(4-(methylthio)phenyl)-5-phenyl-1H-pyrazole-3,4-dicarboxylate (C22H22N2O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. 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), Diethyl 1-(4-(methylthio)phenyl)-5-phenyl-1H-pyrazole-3,4-dicarboxylate 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.
