Structurally, YDB1AQ7N4L 140695-21-2 T 593 Osutidine [INN] GenBank M36922 Methanesulfonamide, N-(((2-hydroxy-2-(4-hydroxyphenyl)ethyl)amino)((2-(((5-((methylamino)methyl)-2-furanyl)methyl)thio)ethyl)amino)methylene)-, (E)- Osutidine (+-)-N-((E)-((p,beta-Dihydroxyphenethyl)amino)((2-((5-((methylamino)methyl)furfuryl)thio)ethyl)amino)methylene)methanesulfonamide CCRIS 8408 UNII-YDB1AQ7N4L T-593 T593 (C19H28N4O5S2) 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 456.58 g/mol, it falls into the moderately-high-molecular-weight range. 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.
