Chemical Structure
Description
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 7-Nitrothieno[3,2-b]pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.18 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).
7-Nitrothieno[3,2-b]pyridine (CAS 104273-31-6), molecular formula C7H4N2O2S and molecular weight 180.18 g/mol, is a CATO reference standard with documented purity and traceability.
