Chemical Structure
Description
The occurrence of 4-Chloro-n-[3-(dimethylamino)propyl]-3-nitrobenzene-1-sulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, 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.
CATO supplies 4-Chloro-n-[3-(dimethylamino)propyl]-3-nitrobenzene-1-sulfonamide (CAS 53803-81-9), a certified reference material (molecular formula C11H16ClN3O4S, MW 321.78 g/mol) for analytical method development and quality control.
4-Chloro-n-[3-(dimethylamino)propyl]-3-nitrobenzene-1-sulfonamide (C11H16ClN3O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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-Chloro-n-[3-(dimethylamino)propyl]-3-nitrobenzene-1-sulfonamide 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.
