Chemical Structure
Description
6-Bromo-5-methoxyisoindolin-1-one (CAS 1427360-45-9) is a high-purity analytical reference standard with the molecular formula C9H8BrNO2 and a molecular weight of 242.07 g/mol.
6-Bromo-5-methoxyisoindolin-1-one (C9H8BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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), 6-Bromo-5-methoxyisoindolin-1-one 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.
