Chemical Structure

Gold, (pentachlorophenyl)(triethylphosphine)- CAS 62201-21-2 chemical structure

Description

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.

Gold, (pentachlorophenyl)(triethylphosphine)- (CAS 62201-21-2) is a high-purity analytical reference standard with the molecular formula C12H15AuCl5P and a molecular weight of 564.45 g/mol.

The molecular framework of Gold, (pentachlorophenyl)(triethylphosphine)- (C12H15AuCl5P) is characterized by organophosphorus functionality, chlorine substitution. 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
