Chloro[(1,2,3,4,5,6-η)-2,2'',4,4'',6,6''-hexamethyl[1,1':3',1''-terphenyl]-2'-thiolato-κS][triisopropylphosphine-κP]ruthenium(II) CAS 1621182-04-4 chemical structure

Description

As a certified reference material (CRM), Chloro[(1,2,3,4,5,6-η)-2,2'',4,4'',6,6''-hexamethyl[1,1':3',1''-terphenyl]-2'-thiolato-κS][triisopropylphosphine-κP]ruthenium(II) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Chloro[(1,2,3,4,5,6-η)-2,2'',4,4'',6,6''-hexamethyl[1,1':3',1''-terphenyl]-2'-thiolato-κS][triisopropylphosphine-κP]ruthenium(II) (CAS 1621182-04-4) is a high-purity analytical reference standard with the molecular formula C24H25ClRuSC9H21P and a molecular weight of 642.28 g/mol.

Owing to sulfur-containing functionality, organophosphorus functionality, chlorine substitution, a polycyclic aromatic system, Chloro[(1,2,3,4,5,6-η)-2,2'',4,4'',6,6''-hexamethyl[1,1':3',1''-terphenyl]-2'-thiolato-κS][triisopropylphosphine-κP]ruthenium(II) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 642.28 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).

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.
