Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, 1-FLUORO-2-(METHYLTHIO)BENZENE 2-FLUOROPHENYL METHYL SULFIDE 2-Fluorothioanisole 655-20-9 AS04284 O-FLUOROTHIOANISOLE is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.19 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).
