Chemical Structure
Description
As a certified reference material (CRM), [1,1'-Biphenyl]-2-yl(4-(dimethylamino)phenyl)(methyl)phosphineoxide 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 [1,1'-Biphenyl]-2-yl(4-(dimethylamino)phenyl)(methyl)phosphineoxide (CAS 94861-77-5), a certified reference material (molecular formula C21H22NOP, MW 335.38 g/mol) for analytical method development and quality control.
The molecular framework of [1,1'-Biphenyl]-2-yl(4-(dimethylamino)phenyl)(methyl)phosphineoxide (C21H22NOP) is characterized by a steroid core, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
