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.
(SP-5-41)-Dichloro[1-(2,6-diethylphenyl)-3,3-dimethyl-5-(1-methylethyl)-2-pyrrolidinylidene][[2-(1-methylethoxy-κO)phenyl]methylene-κC]ruthenium (CAS 1459791-98-0), molecular formula C30H43Cl2NRu and molecular weight 589.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, (SP-5-41)-Dichloro[1-(2,6-diethylphenyl)-3,3-dimethyl-5-(1-methylethyl)-2-pyrrolidinylidene][[2-(1-methylethoxy-κO)phenyl]methylene-κC]ruthenium is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 589.65 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).
As a certified reference material (CRM), (SP-5-41)-Dichloro[1-(2,6-diethylphenyl)-3,3-dimethyl-5-(1-methylethyl)-2-pyrrolidinylidene][[2-(1-methylethoxy-κO)phenyl]methylene-κC]ruthenium 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.
