Chemical Structure
Description
The occurrence of Dibromochloro(triphenylphosphine)gold is closely related to organophosphorus functionality, chlorine/bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Dibromochloro(triphenylphosphine)gold (CAS 32425-13-1), a certified reference material (molecular formula C18H15AuBr2ClP, MW 654.51 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, chlorine/bromine substitution, a polycyclic aromatic system, Dibromochloro(triphenylphosphine)gold is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 654.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
