Compared with other compounds in its class, the molecular weight of 385.43 g/mol gives N-[2-(Benzenesulfonyl)ethyl]-2-(4-fluorobenzenesulfonyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-[2-(Benzenesulfonyl)ethyl]-2-(4-fluorobenzenesulfonyl)acetamide (CAS 337923-51-0), molecular formula C16H16FNO5S2 and molecular weight 385.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-[2-(Benzenesulfonyl)ethyl]-2-(4-fluorobenzenesulfonyl)acetamide (C16H16FNO5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 385.43 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
