[(2R,3R,4S,5R,6S)-4,5,6-triacetoxy-2-[[tert-butyl(diphenyl)silyl]oxymethyl]tetrahydropyran-3-yl] acetate (CAS 894415-91-9), molecular formula C30H38O10Si and molecular weight 586.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, [(2R,3R,4S,5R,6S)-4,5,6-triacetoxy-2-[[tert-butyl(diphenyl)silyl]oxymethyl]tetrahydropyran-3-yl] acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 586.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
