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 (3-Chlorophenyl)[2-[4-(1,1-dimethylethyl)phenyl]-2-oxoethyl][1,2-phenylenebis[diphenylphosphine-κP]]palladium.
(3-Chlorophenyl)[2-[4-(1,1-dimethylethyl)phenyl]-2-oxoethyl][1,2-phenylenebis[diphenylphosphine-κP]]palladium (CAS 727722-26-1), molecular formula C48H43ClOP2Pd and molecular weight 839.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-Chlorophenyl)[2-[4-(1,1-dimethylethyl)phenyl]-2-oxoethyl][1,2-phenylenebis[diphenylphosphine-κP]]palladium (C48H43ClOP2Pd) is characterized by organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
