[1,1':2',1'':2'',1'''-Quaterphenyl]-2-yl(4-(Dimethylamino)phenyl)(methyl)phosphineoxide CAS 105521-34-4

Description

CATO manufactures [1,1':2',1'':2'',1'''-Quaterphenyl]-2-yl(4-(Dimethylamino)phenyl)(methyl)phosphineoxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

[1,1':2',1'':2'',1'''-Quaterphenyl]-2-yl(4-(Dimethylamino)phenyl)(methyl)phosphineoxide (CAS 105521-34-4) is a high-purity analytical reference standard with the molecular formula C33H30NOP and a molecular weight of 487.57 g/mol.

The molecular framework of [1,1':2',1'':2'',1'''-Quaterphenyl]-2-yl(4-(Dimethylamino)phenyl)(methyl)phosphineoxide (C33H30NOP) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, 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.

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.
