(S)-3,3'-Dimethyl-[1,1'-binaphthalene]-2,2'-diol CAS 55515-99-6

Description

The occurrence of (S)-3,3'-Dimethyl-[1,1'-binaphthalene]-2,2'-diol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-3,3'-Dimethyl-[1,1'-binaphthalene]-2,2'-diol (CAS 55515-99-6) is a high-purity analytical reference standard with the molecular formula C22H18O2 and a molecular weight of 314.38 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, (S)-3,3'-Dimethyl-[1,1'-binaphthalene]-2,2'-diol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.38 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).
