(1S,4bR,5R,6aR,10aR,10bR,12aR)-1-(Furan-3-yl)-1-hydroxy-4b,7,7,10a,12a-pentamethyl-3,8-dioxo-3,4b,5,6,6a,7,8,10a,10b,11,12,12a-dodecahydro-1H-naphtho[2,1-f]isochromen-5-yl acetate (CAS 89366-02-9) is a high-purity analytical reference standard with the molecular formula C28H34O7 and a molecular weight of 482.57 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (1S,4bR,5R,6aR,10aR,10bR,12aR)-1-(Furan-3-yl)-1-hydroxy-4b,7,7,10a,12a-pentamethyl-3,8-dioxo-3,4b,5,6,6a,7,8,10a,10b,11,12,12a-dodecahydro-1H-naphtho[2,1-f]isochromen-5-yl acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 482.57 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.
