Chemical Structure
Description
The occurrence of N1-(4-Nitrophenyl)-N1-phenyloxalamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N1-(4-Nitrophenyl)-N1-phenyloxalamide (CAS 22486-74-4), molecular formula C14H11N3O4 and molecular weight 285.25 g/mol, is a CATO reference standard with documented purity and traceability.
N1-(4-Nitrophenyl)-N1-phenyloxalamide (C14H11N3O4) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
CATO manufactures N1-(4-Nitrophenyl)-N1-phenyloxalamide 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.
