Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 302.00 g/mol gives Ethyl 4-Bromo-2-(2-bromoethyl)butyrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 4-Bromo-2-(2-bromoethyl)butyrate (CAS 857778-39-3) is a high-purity analytical reference standard with the molecular formula C8H14Br2O2 and a molecular weight of 302.00 g/mol.
Ethyl 4-Bromo-2-(2-bromoethyl)butyrate (C8H14Br2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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.
