Chemical Structure
Description
As a certified reference material (CRM), (E)-N-Cyclohexyl-N'-[(4-methylphenyl)methyl]-N''-phenylguanidine 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.
CATO supplies (E)-N-Cyclohexyl-N'-[(4-methylphenyl)methyl]-N''-phenylguanidine (CAS 338400-53-6), a certified reference material (molecular formula C21H27N3, MW 321.46 g/mol) for analytical method development and quality control.
The molecular framework of (E)-N-Cyclohexyl-N'-[(4-methylphenyl)methyl]-N''-phenylguanidine (C21H27N3) 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.
