Dichloro(3-methyl-2-butenylidene)bis(tricyclopentylphosphine)ruthenium(II) CAS 220883-08-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dichloro(3-methyl-2-butenylidene)bis(tricyclopentylphosphine)ruthenium(II).

CATO supplies Dichloro(3-methyl-2-butenylidene)bis(tricyclopentylphosphine)ruthenium(II) (CAS 220883-08-9), a certified reference material (molecular formula C15H27PCl2RuC5H8, MW 478.44 g/mol) for analytical method development and quality control.

Structurally, Dichloro(3-methyl-2-butenylidene)bis(tricyclopentylphosphine)ruthenium(II) (C15H27PCl2RuC5H8) contains organophosphorus functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 478.44 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
