[N-[(1R,2R)-2-Amino-1,2-diphenylethyl]-4-methylbenzenesulfonamidato-κN][(1,2,3,4,5,6-η)-1-methyl-4-(1-methylethyl)benzene]ruthenium CAS 195516-84-8

Description

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.

[N-[(1R,2R)-2-Amino-1,2-diphenylethyl]-4-methylbenzenesulfonamidato-κN][(1,2,3,4,5,6-η)-1-methyl-4-(1-methylethyl)benzene]ruthenium (CAS 195516-84-8), molecular formula C21H20N2O2RuSC10H14 and molecular weight 599.75 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [N-[(1R,2R)-2-Amino-1,2-diphenylethyl]-4-methylbenzenesulfonamidato-κN][(1,2,3,4,5,6-η)-1-methyl-4-(1-methylethyl)benzene]ruthenium (C21H20N2O2RuSC10H14) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
