Structurally, (S)-2-(3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-1,1-dioxidotetrahydrothiophen-3-yl)acetic acid (C21H21NO6S) 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 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 415.46 g/mol, it falls into the moderately-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).
(S)-2-(3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-1,1-dioxidotetrahydrothiophen-3-yl)acetic acid (CAS 2381096-41-7), molecular formula C21H21NO6S and molecular weight 415.46 g/mol, is a CATO reference standard with documented purity and traceability.
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.
