Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system, 6-Chlorothiazolo[4,5-b]pyridine-2-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.68 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).
6-Chlorothiazolo[4,5-b]pyridine-2-thiol (CAS 488742-54-7), molecular formula C6H3ClN2S2 and molecular weight 202.68 g/mol, is a CATO reference standard with documented purity and traceability.
