Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 325.45 g/mol gives 4-Cyano-4''-pentyl-p-terphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Cyano-4''-pentyl-p-terphenyl (CAS 54211-46-0), molecular formula C24H23N and molecular weight 325.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Cyano-4''-pentyl-p-terphenyl (C24H23N) 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.
As a certified reference material (CRM), 4-Cyano-4''-pentyl-p-terphenyl 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.
