Description
CATO manufactures N-Ethyl-4-nitro-N-phenylbenzenesulfonamide 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.
N-Ethyl-4-nitro-N-phenylbenzenesulfonamide (CAS 211675-98-8), molecular formula C14H14N2O4S and molecular weight 306.34 g/mol, is a CATO reference standard with documented purity and traceability.
N-Ethyl-4-nitro-N-phenylbenzenesulfonamide (C14H14N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
