Chemical Structure
Description
5-(4-(1H-Imidazol-1-yl)phenyl)-1-phenyl-1H-pyrazole (CAS 321385-61-9), molecular formula C18H14N4 and molecular weight 286.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(4-(1H-Imidazol-1-yl)phenyl)-1-phenyl-1H-pyrazole (C18H14N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
CATO manufactures 5-(4-(1H-Imidazol-1-yl)phenyl)-1-phenyl-1H-pyrazole 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.
