Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [(1R)-1-Methyl-2-oxo-2-phenylethyl](2-methylphenyl)[1,2-phenylenebis[diphenylphosphine-κP]]palladium.
CATO supplies [(1R)-1-Methyl-2-oxo-2-phenylethyl](2-methylphenyl)[1,2-phenylenebis[diphenylphosphine-κP]]palladium (CAS 351531-11-8), a certified reference material (molecular formula C46H40OP2Pd, MW 777.18 g/mol) for analytical method development and quality control.
Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system, [(1R)-1-Methyl-2-oxo-2-phenylethyl](2-methylphenyl)[1,2-phenylenebis[diphenylphosphine-κP]]palladium is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 777.18 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.
