Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies {1,2-Bis(diphenylphosphino)ethane}di(phenylthio)palladium(II) (CAS 33971-07-2), a certified reference material (molecular formula C38H34P2PdS2, MW 723.17 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, organophosphorus functionality, a polycyclic aromatic system, {1,2-Bis(diphenylphosphino)ethane}di(phenylthio)palladium(II) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 723.17 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.
