Chemical Structure
Description
(SP-4-3)-Ethynyldimethyl(triphenylphosphine)gold (CAS 850513-39-2) is a high-purity analytical reference standard with the molecular formula C22H22AuP and a molecular weight of 514.35 g/mol.
The molecular framework of (SP-4-3)-Ethynyldimethyl(triphenylphosphine)gold (C22H22AuP) 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.
As a certified reference material (CRM), (SP-4-3)-Ethynyldimethyl(triphenylphosphine)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.
