4-((1,4-Dioxo-1,4-dihydronaphthalen-2-yl)amino)benzenesulfonamide CAS 19992-50-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((1,4-Dioxo-1,4-dihydronaphthalen-2-yl)amino)benzenesulfonamide.

CATO supplies 4-((1,4-Dioxo-1,4-dihydronaphthalen-2-yl)amino)benzenesulfonamide (CAS 19992-50-8), a certified reference material (molecular formula C16H12N2O4S, MW 328.34 g/mol) for analytical method development and quality control.

The molecular framework of 4-((1,4-Dioxo-1,4-dihydronaphthalen-2-yl)amino)benzenesulfonamide (C16H12N2O4S) is characterized by a flavonoid core, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures 4-((1,4-Dioxo-1,4-dihydronaphthalen-2-yl)amino)benzenesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
