Chemical Structure
Description
The occurrence of Chloro[tris(4-fluorophenyl)phosphine]gold is closely related to organophosphorus functionality, fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Chloro[tris(4-fluorophenyl)phosphine]gold (CAS 53230-28-7) is a high-purity analytical reference standard with the molecular formula C18H12AuClF3P and a molecular weight of 548.68 g/mol.
Owing to organophosphorus functionality, fluorine/chlorine substitution, a polycyclic aromatic system, Chloro[tris(4-fluorophenyl)phosphine]gold is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 548.68 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
