Chemical Structure
Description
As a certified reference material (CRM), Chloro[tris(2,3,4,5,6-pentafluorophenyl)phosphine-κP]gold 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.
Chloro[tris(2,3,4,5,6-pentafluorophenyl)phosphine-κP]gold (CAS 37095-26-4) is a high-purity analytical reference standard with the molecular formula C18AuClF15P and a molecular weight of 764.56 g/mol.
The molecular framework of Chloro[tris(2,3,4,5,6-pentafluorophenyl)phosphine-κP]gold (C18AuClF15P) is characterized by organophosphorus functionality, fluorine/chlorine substitution, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
