Chemical Structure
Description
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.
Palladium, chloro[(9,9-dimethyl-9H-xanthene-4,5-diyl)bis[diphenylphosphine-κP]](η3-2-propenyl)- (CAS 879689-28-8) is a high-purity analytical reference standard with the molecular formula C42H37ClOP2Pd and a molecular weight of 761.56 g/mol.
Structurally, Palladium, chloro[(9,9-dimethyl-9H-xanthene-4,5-diyl)bis[diphenylphosphine-κP]](η3-2-propenyl)- (C42H37ClOP2Pd) contains organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 761.56 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
