N-[(E)-2-(Benzenesulfonyl)-2-(6-chloropyridin-3-yl)ethenyl]-4-methoxyaniline CAS 478048-55-4

Description

The occurrence of N-[(E)-2-(Benzenesulfonyl)-2-(6-chloropyridin-3-yl)ethenyl]-4-methoxyaniline is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-[(E)-2-(Benzenesulfonyl)-2-(6-chloropyridin-3-yl)ethenyl]-4-methoxyaniline (CAS 478048-55-4) is a high-purity analytical reference standard with the molecular formula C20H17ClN2O3S and a molecular weight of 400.88 g/mol.

Structurally, N-[(E)-2-(Benzenesulfonyl)-2-(6-chloropyridin-3-yl)ethenyl]-4-methoxyaniline (C20H17ClN2O3S) 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 400.88 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
