(2R,3R)-Dimethyl 2-bromo-3-hydroxysuccinate (CAS 749917-66-6) is a high-purity analytical reference standard with the molecular formula C6H9BrO5 and a molecular weight of 241.04 g/mol.
(2R,3R)-Dimethyl 2-bromo-3-hydroxysuccinate (C6H9BrO5) contains a carbohydrate-derived structure, 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.
As a certified reference material (CRM), (2R,3R)-Dimethyl 2-bromo-3-hydroxysuccinate 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.
