Chemical Structure
Description
6-Bromo-3-fluoro-2-nitroaniline (CAS 1804841-33-5) is a high-purity analytical reference standard with the molecular formula C6H4BrFN2O2 and a molecular weight of 235.01 g/mol.
6-Bromo-3-fluoro-2-nitroaniline (C6H4BrFN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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), 6-Bromo-3-fluoro-2-nitroaniline 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.
