Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 227.05 g/mol gives 1-(4-Bromophenyl)propane-1,2-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(4-Bromophenyl)propane-1,2-dione (CAS 10557-20-7), molecular formula C9H7BrO2 and molecular weight 227.05 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Bromophenyl)propane-1,2-dione (C9H7BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(4-Bromophenyl)propane-1,2-dione 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.
