2-amino-3,1,4$l^{5}-[1,2$l^{5},4]thiadiazolo[2,3-a][1$l^{5}]pyridin-4-ylium chloride (CAS 36273-97-9), molecular formula C6H6N3SCl and molecular weight 187.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system, 2-amino-3,1,4$l^{5}-[1,2$l^{5},4]thiadiazolo[2,3-a][1$l^{5}]pyridin-4-ylium chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.65 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
