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.
Sodium 3-(2-((3-(3-sulfonatopropyl)benzo[4,5]thieno[2,3-d]thiazol-3-ium-2-yl)methylene)benzo[d]thiazol-3(2H)-yl)propane-1-sulfonate (CAS 183365-76-6) is a high-purity analytical reference standard with the molecular formula C23H21N2O6S5Na and a molecular weight of 604.72 g/mol.
Structurally, Sodium 3-(2-((3-(3-sulfonatopropyl)benzo[4,5]thieno[2,3-d]thiazol-3-ium-2-yl)methylene)benzo[d]thiazol-3(2H)-yl)propane-1-sulfonate (C23H21N2O6S5Na) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 604.72 g/mol, it falls into the high-molecular-weight range. 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.
