Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 3-(Carboxymethyl)-2-methylthieno[2,3-d]thiazol-3-ium bromide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.18 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).
3-(Carboxymethyl)-2-methylthieno[2,3-d]thiazol-3-ium bromide (CAS 1674389-40-2) is a high-purity analytical reference standard with the molecular formula C8H8NO2S2Br and a molecular weight of 294.18 g/mol.
