Chemical Structure
Description
As a certified reference material (CRM), 2,2'-Bis((diphenylphosphaneyl)methyl)-1,1'-binaphthalene 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 2,2'-Bis((diphenylphosphaneyl)methyl)-1,1'-binaphthalene (CAS 128347-41-1), a certified reference material (molecular formula C46H36P2, MW 650.73 g/mol) for analytical method development and quality control.
The molecular framework of 2,2'-Bis((diphenylphosphaneyl)methyl)-1,1'-binaphthalene (C46H36P2) is characterized by organophosphorus functionality, a polycyclic aromatic system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
