Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.10 g/mol gives DIethyl 4-bromobutylphosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
DIethyl 4-bromobutylphosphonate (CAS 63075-66-1), molecular formula C8H18BrO3P and molecular weight 273.10 g/mol, is a CATO reference standard with documented purity and traceability.
DIethyl 4-bromobutylphosphonate (C8H18BrO3P) contains a phosphonate group, a carboxylic acid 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
