Bis(acetato)aqua[(S,S)-4,6-bis(4-isopropyl-2-oxazolin-2-yl)-m-xylene]rhodium (CAS 929896-28-6) is a high-purity analytical reference standard with the molecular formula C20H27N2O2RhC2H3O2H2O and a molecular weight of 507.42 g/mol.
Bis(acetato)aqua[(S,S)-4,6-bis(4-isopropyl-2-oxazolin-2-yl)-m-xylene]rhodium (C20H27N2O2RhC2H3O2H2O) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
