(8'-Hydroxy-[1,1'-binaphthalen]-8-yl)diphenylphosphineoxide CAS 181130-03-0

Description

Compared with other compounds in its class, the molecular weight of 470.50 g/mol gives (8'-Hydroxy-[1,1'-binaphthalen]-8-yl)diphenylphosphineoxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (8'-Hydroxy-[1,1'-binaphthalen]-8-yl)diphenylphosphineoxide (CAS 181130-03-0), a certified reference material (molecular formula C32H23O2P, MW 470.50 g/mol) for analytical method development and quality control.

The molecular framework of (8'-Hydroxy-[1,1'-binaphthalen]-8-yl)diphenylphosphineoxide (C32H23O2P) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), (8'-Hydroxy-[1,1'-binaphthalen]-8-yl)diphenylphosphineoxide 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.
