Chemical Structure
Description
The molecular framework of 4′-(Phenylmethoxy)[1,1′-biphenyl]-4-carbonitrile (C20H15NO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4′-(Phenylmethoxy)[1,1′-biphenyl]-4-carbonitrile (CAS 117571-49-0), molecular formula C20H15NO and molecular weight 285.34 g/mol, is a CATO reference standard with documented purity and traceability.
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′-(Phenylmethoxy)[1,1′-biphenyl]-4-carbonitrile 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.
