Chemical Structure
Description
As a certified reference material (CRM), (1,3-Dioxoisoindolin-2-yl)methyl 2-bromo-2-methylpropanoate 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.
(1,3-Dioxoisoindolin-2-yl)methyl 2-bromo-2-methylpropanoate (CAS 903562-13-0), molecular formula C13H12BrNO4 and molecular weight 326.14 g/mol, is a CATO reference standard with documented purity and traceability.
(1,3-Dioxoisoindolin-2-yl)methyl 2-bromo-2-methylpropanoate (C13H12BrNO4) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
