The occurrence of Methyl 5-iodothiazole-4-carboxylate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 5-iodothiazole-4-carboxylate (CAS 1346818-75-4), molecular formula C5H4INO2S and molecular weight 269.06 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, Methyl 5-iodothiazole-4-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.06 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).
