1-[4-(dimethylamino)phenyl]-3-{2,6-dimethylimidazo[2,1-b][1,3]thiazol-5-yl}prop-2-en-1-one (CAS 1111591-52-6), molecular formula C18H19N3OS and molecular weight 325.43 g/mol, is a CATO reference standard with documented purity and traceability.
1-[4-(dimethylamino)phenyl]-3-{2,6-dimethylimidazo[2,1-b][1,3]thiazol-5-yl}prop-2-en-1-one (C18H19N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
