Chemical Structure
Description
The occurrence of 4-Hydroxy-3-nitrobenzenesulfonamide is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Hydroxy-3-nitrobenzenesulfonamide (CAS 24855-58-1), a certified reference material (molecular formula C6H6N2O5S, MW 218.19 g/mol) for analytical method development and quality control.
4-Hydroxy-3-nitrobenzenesulfonamide (C6H6N2O5S) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 4-Hydroxy-3-nitrobenzenesulfonamide 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.
