9-Phosphabicyclo[3.3.1]nonane, 9,9′-[[1,1′-biphenyl]-2,2′-diylbis(methylene)]bis- CAS 525602-69-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9-Phosphabicyclo[3.3.1]nonane, 9,9′-[[1,1′-biphenyl]-2,2′-diylbis(methylene)]bis-.

9-Phosphabicyclo[3.3.1]nonane, 9,9′-[[1,1′-biphenyl]-2,2′-diylbis(methylene)]bis- (CAS 525602-69-1), molecular formula C32H40P2 and molecular weight 486.61 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 9-Phosphabicyclo[3.3.1]nonane, 9,9′-[[1,1′-biphenyl]-2,2′-diylbis(methylene)]bis- (C32H40P2) 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 9-Phosphabicyclo[3.3.1]nonane, 9,9′-[[1,1′-biphenyl]-2,2′-diylbis(methylene)]bis- 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.
