Chemical Structure
Description
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Thioxo-2,3-dihydrothiazol-5-yl acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.23 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).
2-Thioxo-2,3-dihydrothiazol-5-yl acetate (CAS 149432-47-3), molecular formula C5H5NO2S2 and molecular weight 175.23 g/mol, is a CATO reference standard with documented purity and traceability.
