Chemical Structure

Chloro[(R)-(-)-5,5'-bis[bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphino]-4,4'-bi-1,3-benzodioxole](p-cymene)ruthenium(II) Chloride CAS 944451-32-5 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.

CATO supplies Chloro[(R)-(-)-5,5'-bis[bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphino]-4,4'-bi-1,3-benzodioxole](p-cymene)ruthenium(II) Chloride (CAS 944451-32-5), a certified reference material (molecular formula C74H100ClO8P2RuC10H20Cl, MW 1491.79 g/mol) for analytical method development and quality control.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, Chloro[(R)-(-)-5,5'-bis[bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphino]-4,4'-bi-1,3-benzodioxole](p-cymene)ruthenium(II) Chloride is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1491.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
