Description

Compared with other compounds in its class, the molecular weight of 413.92 g/mol gives N-(4'-Cyano-[1,1'-biphenyl]-3-yl)-N-(pyridin-3-ylmethyl)ethanesulfonamide hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(4'-Cyano-[1,1'-biphenyl]-3-yl)-N-(pyridin-3-ylmethyl)ethanesulfonamide hydrochloride (CAS 856702-40-4) is a high-purity analytical reference standard with the molecular formula C21H19N3O2SHCl and a molecular weight of 413.92 g/mol.

The molecular framework of N-(4'-Cyano-[1,1'-biphenyl]-3-yl)-N-(pyridin-3-ylmethyl)ethanesulfonamide hydrochloride (C21H19N3O2SHCl) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
