Description

The occurrence of 62758-12-7 Sodium p-((p-(diethylamino)phenyl)azo)benzenesulphonate Benzenesulfonic acid, 4-(2-(4-(diethylamino)phenyl)diazenyl)-, sodium salt (1:1) Benzenesulfonic acid, 4-((4-(diethylamino)phenyl)azo)-, sodium salt EINECS 263-716-4 is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 62758-12-7 Sodium p-((p-(diethylamino)phenyl)azo)benzenesulphonate Benzenesulfonic acid, 4-(2-(4-(diethylamino)phenyl)diazenyl)-, sodium salt (1:1) Benzenesulfonic acid, 4-((4-(diethylamino)phenyl)azo)-, sodium salt EINECS 263-716-4 (CAS 62758-12-7), a certified reference material (molecular formula C16H31N3O3S, MW 345.50 g/mol) for analytical method development and quality control.

The molecular framework of 62758-12-7 Sodium p-((p-(diethylamino)phenyl)azo)benzenesulphonate Benzenesulfonic acid, 4-(2-(4-(diethylamino)phenyl)diazenyl)-, sodium salt (1:1) Benzenesulfonic acid, 4-((4-(diethylamino)phenyl)azo)-, sodium salt EINECS 263-716-4 (C16H31N3O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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 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.
