Chemical Structure
Description
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, (R)-1-(Isothiazol-5-yl)ethan-1-ol is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.18 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).
