Description

As a certified reference material (CRM), Propanoic acid, 2-bromo-2-methyl-, 2,5-dioxo-1-pyrrolidinyl ester 728034-24-0 A1-04783 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.

Propanoic acid, 2-bromo-2-methyl-, 2,5-dioxo-1-pyrrolidinyl ester 728034-24-0 A1-04783 (CAS 728034-24-0) is a high-purity analytical reference standard with the molecular formula C8H10BrNO4 and a molecular weight of 264.07 g/mol.

Propanoic acid, 2-bromo-2-methyl-, 2,5-dioxo-1-pyrrolidinyl ester 728034-24-0 A1-04783 (C8H10BrNO4) 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.
