Description
2-((4-Benzyl-1,1-dioxido-4H-benzo[e][1,2,4]thiadiazin-3-yl)thio)-N-(2-methoxyphenyl)acetamide (CAS 951486-26-3), molecular formula C23H21N3O4S2 and molecular weight 467.56 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-((4-Benzyl-1,1-dioxido-4H-benzo[e][1,2,4]thiadiazin-3-yl)thio)-N-(2-methoxyphenyl)acetamide (C23H21N3O4S2) 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 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 467.56 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).
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.
