Chemical Structure
Description
Owing to a flavonoid core, a hydroxyl group, an ether linkage, (S)-(-)-2,2’-Bis(methoxymethoxy)-1,1’-binaphthalene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.43 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).
(S)-(-)-2,2’-Bis(methoxymethoxy)-1,1’-binaphthalene (CAS 142128-92-5), molecular formula C24H22O4 and molecular weight 374.43 g/mol, is a CATO reference standard with documented purity and traceability.
