Chemical Structure
Description
The occurrence of Tris(triphenylphosphine)palladium is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Tris(triphenylphosphine)palladium (CAS 28516-49-6), a certified reference material (molecular formula C54H45P3Pd, MW 893.28 g/mol) for analytical method development and quality control.
The molecular framework of Tris(triphenylphosphine)palladium (C54H45P3Pd) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Tris(triphenylphosphine)palladium 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.
