Chemical Structure
Description
CATO supplies 2-Bromo-1-(4-bromo-3-nitrophenyl)ethanone (CAS 22055-48-7), a certified reference material (molecular formula C8H5Br2NO3, MW 322.94 g/mol) for analytical method development and quality control.
2-Bromo-1-(4-bromo-3-nitrophenyl)ethanone (C8H5Br2NO3) 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.
As a certified reference material (CRM), 2-Bromo-1-(4-bromo-3-nitrophenyl)ethanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
