4-Iodothieno[2,3-c]pyridin-7-ol (CAS 1360902-41-5) is a high-purity analytical reference standard with the molecular formula C7H4INOS and a molecular weight of 277.08 g/mol.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 4-Iodothieno[2,3-c]pyridin-7-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.08 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
