Chemical Structure
Description
The occurrence of (2-Methylphenyl)[2-oxo-2-[4-(trifluoromethyl)phenyl]ethyl][1,2-phenylenebis[diphenylphosphine-κP]]palladium is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2-Methylphenyl)[2-oxo-2-[4-(trifluoromethyl)phenyl]ethyl][1,2-phenylenebis[diphenylphosphine-κP]]palladium (CAS 351531-16-3), a certified reference material (molecular formula C46H37F3OP2Pd, MW 831.15 g/mol) for analytical method development and quality control.
Structurally, (2-Methylphenyl)[2-oxo-2-[4-(trifluoromethyl)phenyl]ethyl][1,2-phenylenebis[diphenylphosphine-κP]]palladium (C46H37F3OP2Pd) contains organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 27.0, corresponding to approximately 27 ring(s) or double-bond equivalent(s). With a molecular weight of 831.15 g/mol, it falls into the high-molecular-weight range. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
