N-(2,4-Dichlorophenyl)-5-[4-(4-methylpiperazin-1-yl)phenyl]-1H-pyrazole-1-carboxamide CAS 321998-94-1

Description

CATO supplies N-(2,4-Dichlorophenyl)-5-[4-(4-methylpiperazin-1-yl)phenyl]-1H-pyrazole-1-carboxamide (CAS 321998-94-1), a certified reference material (molecular formula C21H21Cl2N5O, MW 430.33 g/mol) for analytical method development and quality control.

The molecular framework of N-(2,4-Dichlorophenyl)-5-[4-(4-methylpiperazin-1-yl)phenyl]-1H-pyrazole-1-carboxamide (C21H21Cl2N5O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

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.

CATO manufactures N-(2,4-Dichlorophenyl)-5-[4-(4-methylpiperazin-1-yl)phenyl]-1H-pyrazole-1-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
