Chemical Structure
Description
(4-Methylphenyl)(triphenylphosphine)gold (CAS 40667-81-0), molecular formula C25H23AuP and molecular weight 551.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Methylphenyl)(triphenylphosphine)gold (C25H23AuP) 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.
CATO manufactures (4-Methylphenyl)(triphenylphosphine)gold 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.
