Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, (2S)-Butan-2-yl2-(3-[4-[2-(diethylamino)ethoxy]-3,5-diiodobenzoyl]-1-benzofuran-2-yl)acetate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 703.35 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).
(2S)-Butan-2-yl2-(3-[4-[2-(diethylamino)ethoxy]-3,5-diiodobenzoyl]-1-benzofuran-2-yl)acetate (CAS 335148-45-3), molecular formula C27H31I2NO5 and molecular weight 703.35 g/mol, is a CATO reference standard with documented purity and traceability.
