Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Bis[1,2-bis(diphenylphosphino)ethane]carbonylchloroiridium(I) (CAS 15417-85-3) is a high-purity analytical reference standard with the molecular formula C53H48ClIrOP4 and a molecular weight of 1052.51 g/mol.
Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, Bis[1,2-bis(diphenylphosphino)ethane]carbonylchloroiridium(I) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1052.51 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).
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.
