Chemical Structure
Description
The occurrence of Chlorodihydridotris(triphenylphosphine)iridium is closely related to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Chlorodihydridotris(triphenylphosphine)iridium (CAS 17035-59-5), molecular formula C54H47ClIrP3 and molecular weight 1016.54 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C54H47ClIrP3, Chlorodihydridotris(triphenylphosphine)iridium contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1016.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
