The molecular framework of 21P699C5FC 1312547-19-5 Samatasvir [USAN:INN] Carbamic acid, N-((1R)-2-((2S)-2-(5-(4-(6-(2-((2S)-1-((2S)-2-((methoxycarbonyl)amino)-3-methyl-1-oxobutyl)-2-pyrrolidinyl)-1H-benzimidazol-6-yl)thieno(3,2-b)thien-3-yl)phenyl)-1H-imidazol-2-yl)-1-pyrrolidinyl)-2-oxo-1-phenylethyl)-, methyl ester Methyl N-((1R)-2-((2S)-2-(5-(4-(6-(2-((2S)-1-((2S)-2-((methoxycarbonyl)amino)-3-methylbutanoyl)pyrrolidin-2-yl)-3H-benzimidazol-5-yl)thieno(3,2-b)thiophen-3-yl)phenyl)-1H-imidazol-2-yl)pyrrolidin-1-yl)-2-oxo-1-phenylethyl)carbamate IDX18719 Samatasvir UNII-21P699C5FC IDX 18719 IDX 719 IDX719 IDX-719 (C47H48N8O6S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
