Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (1E)-1-(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)-N-(4-chlorophenyl)methanimine (CAS 320422-65-9), a certified reference material (molecular formula C17H13Cl2N3, MW 330.21 g/mol) for analytical method development and quality control.
The molecular framework of (1E)-1-(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)-N-(4-chlorophenyl)methanimine (C17H13Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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 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).
CATO manufactures (1E)-1-(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)-N-(4-chlorophenyl)methanimine 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.
