Chemical Structure
Description
The occurrence of N-(2,5-DIBROMO-4-NITROPHENYL)ACETAMIDE is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(2,5-DIBROMO-4-NITROPHENYL)ACETAMIDE (CAS 25462-67-3), molecular formula C8H6Br2N2O3 and molecular weight 337.95 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(2,5-DIBROMO-4-NITROPHENYL)ACETAMIDE (C8H6Br2N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 N-(2,5-DIBROMO-4-NITROPHENYL)ACETAMIDE 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.
