Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(4-((2-Chlorobenzyl)oxy)phenyl)-N'-(2-ethoxybenzylidene)-1H-pyrazole-3-carbohydrazide.
CATO supplies 5-(4-((2-Chlorobenzyl)oxy)phenyl)-N'-(2-ethoxybenzylidene)-1H-pyrazole-3-carbohydrazide (CAS 634897-07-7), a certified reference material (molecular formula C26H23ClN4O3, MW 474.94 g/mol) for analytical method development and quality control.
The molecular framework of 5-(4-((2-Chlorobenzyl)oxy)phenyl)-N'-(2-ethoxybenzylidene)-1H-pyrazole-3-carbohydrazide (C26H23ClN4O3) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-(4-((2-Chlorobenzyl)oxy)phenyl)-N'-(2-ethoxybenzylidene)-1H-pyrazole-3-carbohydrazide 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.
