Chemical Structure
Description
Bis(triphenylphosphine)gold(1+) (CAS 47807-21-6) is a high-purity analytical reference standard with the molecular formula C36H30AuP2 and a molecular weight of 721.54 g/mol.
Owing to organophosphorus functionality, a polycyclic aromatic system, Bis(triphenylphosphine)gold(1+) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 721.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
