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(diphenylphosphino)-4,4'-bi-1,3-benzodioxole](p-cymene)ruthenium(II) chloride, [RuCl(p-cymene)((R)-segphos)]Cl 944451-28-9 (R)-RUCL[(P-CYMENE)(SEGPHOS(R))]CL;(S)-RUCL[(P-CYMENE)(SEGPHOS(R))]CL;CHLORO[(R)-(+)-5,5'-BIS(DIPHENYLPHOSPHINO)-4,4'-BI-1,3-BENZODIOXOLE](P-CYMENE)RUTHENIUM(II) CHLORIDE;CHLORO[(S)-(-)-5,5'-BIS(DIPHENYLPHOSPHINO)-4,4'-BI-1,3-BENZODIOXOLE](P-CYMENE)RUTHENIUM(II) CHLORIDE;[RUCL(P-CYMENE)((R)-SEGPHOS(R))]CL;[RUCL(P-CYMENE)((S)-SEGPHOS(R))]CL;Chloro[(R)-(+)-5,5'-bis(diphenylphosphino)-4,4'-bi-1,3-benzodioxole](p-cymene)ruthenium(II) chloride, [RuCl(p-cymene)((R)-segphos)]Cl SC10131 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 953.07 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.
