Chemical Structure
Description
Dimethyl (3-bromo-2-oxopropyl)phosphonate (CAS 87830-69-1), molecular formula C5H10BrO4P and molecular weight 245.01 g/mol, is a CATO reference standard with documented purity and traceability.
Dimethyl (3-bromo-2-oxopropyl)phosphonate (C5H10BrO4P) contains a carbohydrate-derived structure, a phosphate ester group, 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), Dimethyl (3-bromo-2-oxopropyl)phosphonate 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.
