Chemical Structure
Description
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1-(4-Fluorophenyl)-2-(methylthio)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.23 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).
1-(4-Fluorophenyl)-2-(methylthio)ethan-1-one (CAS 122831-40-7), molecular formula C9H9FOS and molecular weight 184.23 g/mol, is a CATO reference standard with documented purity and traceability.
