Chemical Structure
Description
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, Thiophen-2-yl(thiophen-3-yl)methanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.27 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).
Thiophen-2-yl(thiophen-3-yl)methanone (CAS 26453-84-9), molecular formula C9H6OS2 and molecular weight 194.27 g/mol, is a CATO reference standard with documented purity and traceability.
