Chemical Structure
Description
As a certified reference material (CRM), Diphenyl(2-(2-(trimethylsilyl)naphthalen-1-yl)phenyl)phosphane 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.
Diphenyl(2-(2-(trimethylsilyl)naphthalen-1-yl)phenyl)phosphane (CAS 2227375-33-7) is a high-purity analytical reference standard with the molecular formula C31H29PSi and a molecular weight of 460.62 g/mol.
The molecular framework of Diphenyl(2-(2-(trimethylsilyl)naphthalen-1-yl)phenyl)phosphane (C31H29PSi) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
