Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.08 g/mol gives 2-Bromo-N-(2-methyl-5-nitrophenyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-N-(2-methyl-5-nitrophenyl)acetamide (CAS 349121-16-0) is a high-purity analytical reference standard with the molecular formula C9H9BrN2O3 and a molecular weight of 273.08 g/mol.
2-Bromo-N-(2-methyl-5-nitrophenyl)acetamide (C9H9BrN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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 2-Bromo-N-(2-methyl-5-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.
