4-[(5Z)-5-[(Dimethylamino)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]-4-azatricyclo[5.2.1.0^{2,6}]dec-8-ene-3,5-dione (CAS 477766-81-7) is a high-purity analytical reference standard with the molecular formula C15H15N3O3S2 and a molecular weight of 349.43 g/mol.
Based on its molecular formula C15H15N3O3S2, 4-[(5Z)-5-[(Dimethylamino)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]-4-azatricyclo[5.2.1.0^{2,6}]dec-8-ene-3,5-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 349.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
