Chemical Structure
Description
3-(5-Bromo-1-oxo-2-isoindolinyl)piperidine-2,6-dione (CAS 1010100-26-1), molecular formula C13H11BrN2O3 and molecular weight 323.14 g/mol, is a CATO reference standard with documented purity and traceability.
3-(5-Bromo-1-oxo-2-isoindolinyl)piperidine-2,6-dione (C13H11BrN2O3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3-(5-Bromo-1-oxo-2-isoindolinyl)piperidine-2,6-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.
