Description
Compared with other compounds in its class, the molecular weight of 456.98 g/mol gives (E)-N-[2-[[[3-(4-Chlorophenyl)allyl](methyl)amino]methyl]phenyl]-4-methoxybenzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(E)-N-[2-[[[3-(4-Chlorophenyl)allyl](methyl)amino]methyl]phenyl]-4-methoxybenzenesulfonamide (CAS 1283519-40-3), molecular formula C24H25ClN2O3S and molecular weight 456.98 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-N-[2-[[[3-(4-Chlorophenyl)allyl](methyl)amino]methyl]phenyl]-4-methoxybenzenesulfonamide (C24H25ClN2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 456.98 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.
